The three-pointed star has long been synonymous with automotive excellence, and for enthusiasts looking to enter the world of classic cars, the Mercedes Benz W123 offers a compelling entry point. This iconic model, aging gracefully, presents an opportunity to own a piece of German automotive history. While used Mercedes vehicles come in various price ranges, it’s essential to remember that maintenance and spare parts for classic models like the W123 can be a premium. However, for those seeking a blend of timeless design, robust engineering, and a rewarding ownership experience, the W123 remains a sought-after classic, with prices steadily appreciating as well-maintained examples become increasingly rare. For many, particularly in regions like India, the W123 was their first taste of true German automotive engineering and luxury during the mid-1980s, becoming a symbol of success and discerning taste.
The Mercedes Benz W123 is generally considered a solid investment in the classic car market. Left-hand drive (LHD) versions may sometimes offer a more accessible price point due to market variations. It’s crucial to understand that while the W123 generation is known for its reliability, it’s not inexpensive to maintain. Owning one necessitates both specialized mechanical expertise and a committed owner willing to invest in its upkeep. Fortunately, mechanics familiar with the W123’s robust mechanical systems are available in many multi-brand workshops, ensuring that keeping your classic Mercedes in top condition is achievable. Ultimately, the W123 is a special vehicle that delivers on all fronts: striking aesthetics, a luxurious feel, and a uniquely enjoyable driving experience.
Exploring the Mercedes Benz W123 Variants
Introduced in early 1976, the Mercedes Benz W123 was designed as the successor to the W114 generation, and Mercedes officially designated it the 200-280 series, positioning it in the same market segment as today’s E-Class. The W123 model range was diverse, offering several body styles to cater to different needs and preferences. These included: the W123 (4-door sedan), the S123 (estate or station wagon), the C123 (coupe), and the V123 (long-wheelbase sedan). This guide will primarily focus on the W123 sedan, as it was the most prevalent body style imported and sold in many markets. While a few S123 estates can be found, they are considerably rarer.
Within specific markets, diesel variants of the Mercedes Benz W123, such as the 200D, 240D, and 300D, gained significant popularity. Petrol-engine models like the 230E and 280E are less commonly encountered. While the entry-level 200D diesel might feel somewhat underpowered by modern standards, the 300D diesel variant is undeniably a robust performer. The 240D strikes a good balance and is a more frequently found option. The W123 enjoys broad availability in the used car market, and remarkably, a significant number of these vehicles are still in commendable condition, making finding a well-preserved example a real possibility.
Bodywork and Rust Considerations
When evaluating a Mercedes Benz W123, prospective buyers will find a spectrum of conditions, from vehicles needing extensive restoration to those that are roadworthy and some that have already been restored. It is important to remember that rust protection technologies were less advanced when the W123 was originally manufactured. Therefore, allocating a portion of your budget to address potential bodywork issues is prudent. Key areas to inspect for rust include the wheel arches and the leading edges of the fenders. A particularly vulnerable spot across various climates is the underside of the rear fenders. The design of the fenders just behind the rear wheels makes the painted surface susceptible to abrasion from road debris thrown up by the tires. Additionally, the rear window rubber seals can degrade over time, allowing water ingress and leading to rust formation around the rear window or on the pillar trim finishers.
Rust appearing on the lower sections of doors, the spare wheel well, the boot lid, and around jacking points is almost a standard feature of classic Mercedes ownership of this era. The battery tray is also prone to corrosion due to acid leaks, which can progressively erode the paint and initiate rust, potentially leading to costly repairs. It’s also crucial to ensure that the drainage channels beneath the hood hinges are unobstructed. Blockages here can cause water to overflow into the floor pan, leading to further corrosion issues. Inconsistencies in paint finish on different body panels might indicate prior accident repairs. It’s advisable to either avoid such vehicles or negotiate a significantly lower price. While the W123 is known for its robust construction, it’s generally wiser to steer clear of severely rusted examples that are offered at very low prices, as the cost of restoring them to a good condition can be substantial. Although Mercedes-Benz still provides original body panels, purchasing them can be a significant financial outlay.
Engine Longevity and Maintenance
The diesel engines available in the 200D, 240D, and 300D models – two four-cylinder and one five-cylinder respectively – are renowned for their exceptional durability. These engines, with proper and consistent maintenance, are capable of reaching mileages exceeding 500,000 miles. While the 200D is often criticized for being underpowered, the 240D offers a noticeable improvement in performance. The OM616 four-cylinder diesel engine in the 240D is particularly well-regarded for its balance of power and fuel efficiency. Characteristically over-engineered, these engines, with regular oil changes, are incredibly reliable. A known weak point is the rear crankshaft seal, which can leak and potentially lead to oil starvation if not addressed. Spare parts for these engines are readily available. For budget-conscious owners, parts such as piston rings, timing chains, gaskets, and oil filters can even be sourced from suppliers of Force Tempo Traveller components, highlighting the engine’s widespread use and robust design.
The 300D’s OM617 engine, an inline-five diesel, was later offered with turbocharging from 1981 onwards. Common areas for leaks include the cam cover, oil pan, and fuel return lines. It’s important to inspect all fuel injection hoses for leaks, as any fuel leakage could indicate more serious underlying issues. Some play in the linkage between the accelerator and the injection system is normal, but excessive play should be investigated. The glow plug indicator light should illuminate for only a brief period, typically less than 10 seconds. While some diesel smoke is expected, excessive white, black, or blue smoke suggests engine problems. Oil changes should be performed at least every 8,000 kilometers to maintain engine health and longevity.
Transmission Systems: Manual and Automatic
Most Mercedes Benz W123 models imported were equipped with a 5-speed manual transmission. However, it’s noted that this gearbox is not the smoothest by Mercedes standards, described as somewhat notchy and agricultural for a vehicle of its class. Only models produced post-1981 received the 5-speed Getrag 717.4 gearbox; earlier models used a 4-speed transmission. Despite these characteristics, these transmissions are remarkably durable. Any unusual noises like whining or excessive looseness could indicate high mileage and potentially neglected maintenance. The rest of the drivetrain is robust, but component replacements such as a differential rebuild or an original equipment (OE) clutch kit can be expensive. It is always recommended to use OE parts to ensure compatibility and longevity. The 4-speed automatic 722.1 gearbox typically starts in second gear under normal conditions but will engage first gear under full throttle (kick-down) or when the ‘L’ (Low) selector is used. Although a four-speed, it functions primarily as a three-speed in regular driving. Differentials are generally reliable, but it’s wise to regularly check the driveshaft seals as a preventative measure.
Suspension and Steering Checks
When assessing the suspension and steering of a Mercedes Benz W123, begin by checking for excessive play in the steering wheel. If the adjustment range is fully utilized, it may indicate the need for a new steering box, which is a significant expense. Over-tightening the steering box to compensate for wear can also accelerate its deterioration. Often, the actual issue might be related to the steering damper arm. The W123’s comfortable ride can sometimes mask worn shock absorbers, and coil springs are susceptible to cracking or sagging over time. A growling noise from the axles suggests they may require replacement. The rear control arms are prone to rust, particularly where the shocks are mounted, and addressing this may necessitate a complete rear suspension overhaul. Replacing the rear wheel bearings requires a specialized tool and is a task best left to experienced mechanics rather than attempting as a DIY project.
Brake System Inspection
All Mercedes Benz W123 models feature servo-assisted disc brakes on all four wheels. This system is relatively straightforward and generally reliable. Caliper seizure is a potential issue, which can manifest as a spongy brake pedal and reduced braking confidence. Master cylinder failures can occur, but replacements are generally accessible and not overly expensive. Routine maintenance primarily involves checking the brake fluid every two years to ensure it is free from water contamination and air bubbles.
Electrical Systems and Optional Features
While many Mercedes Benz W123 models were produced with a standard level of equipment, those fitted with optional extras have proven to be generally reliable. These optional features often included power windows, central locking, air conditioning, cassette players, and electrically heated seats, among others. Mercedes even offered upgrades to fully automatic climate control, and the most premium option available was a Becker radio telephone. The central locking system is vacuum-operated, which is efficient when functioning correctly. However, vacuum leaks can develop, leading to system malfunctions, such as the vehicle not locking or unlocking properly. Air conditioning systems are prone to leaks, and it’s likely that many older W123s still operate on R12 refrigerant rather than the more modern R134a. It’s also advisable to test the power antenna to ensure it extends and retracts smoothly, either using the car’s controls or the manual switch inside the vehicle.
Interior Condition and Trim
Mercedes Benz offered five primary upholstery options for the W123 interior: MB Tex (the most common), leather, cloth, half cloth, and velour. A wide array of color combinations were available, making it challenging to find matching replacement interiors in good condition. Sourcing exact replacement trim pieces can be nearly impossible. It is important to inspect the front seat bases, which use a sprung design rather than foam for support. These can collapse, particularly on the outer edge of the driver’s seat.
Scrapyards may occasionally offer seats in good condition, but these are rare, especially in some regions. Often, the best solution is to find an upholstery specialist who can rebuild the seat base at a reasonable cost. Check the functionality of all air conditioning vents, ensuring they open and close properly. Inspect carpets and floor pans for signs of water ingress, which could indicate a faulty front windscreen seal—a replaceable component. Loose interior plastic or wooden trim can usually be re-glued, but cracked or missing trim can be very expensive to replace.
Market Prices and Availability Today
The Mercedes Benz W123 began its transition to collectible status relatively recently. There was a period when these cars experienced significant depreciation, with examples changing hands at very low prices in the late 2000s. Some were even scrapped prematurely when maintenance costs exceeded their market value. Vehicle scrappage policies further impacted the availability of these classic Mercedes. However, enthusiast interest in the W123 has surged dramatically, leading to a rapid increase in used market prices.
Despite the price appreciation, a considerable number of W123s are still available, starting at relatively affordable price points. The market includes vehicles in varying states of repair, from heavily deteriorated to driveable, and some that have been fully restored to showroom condition. This range means there’s a Mercedes Benz W123 to fit different budgets. Models manufactured post-1982 are generally more desirable due to a facelift that introduced several upgrades, including power steering as standard, improved rear legroom, a driver’s airbag, and a 5-speed manual gearbox.
