Bodywork: Inspecting for Rust and Damage
When considering a W123 Mercedes for sale, bodywork is a critical area of inspection. Market availability ranges from cars in need of complete restoration to those that are roadworthy, along with some beautifully restored examples. It’s important to remember that rust protection technology was not as advanced when the W123 was manufactured, making rust a common issue. Be prepared to invest in maintaining the bodywork. Key rust-prone areas include wheel arches and the leading edges of the fenders. A particularly vulnerable spot is the underside of the rear fenders, behind the rear wheels, where road debris can chip away paint and initiate rust. Rear window rubber seals also degrade over time, allowing water ingress and leading to rust around the rear window and pillar trims.

Jacking points and surrounding metal are notorious locations for rust to develop on the W123.
Further rust-sensitive areas to check when looking at a W123 Mercedes for sale include the bottom of doors, spare wheel well, boot lid, and jacking points. Battery trays are also susceptible to rust due to acid leakage, which can lead to significant corrosion and costly repairs. Ensure the drainage slots under the hood hinges are clear to prevent water from accumulating and potentially spilling into the floor pan. Inconsistent paintwork on body panels might indicate previous accident damage. It’s wise to avoid heavily rusted cars, even if priced attractively, as restoration can be expensive. While Mercedes-Benz still supplies original panels, the cost can be substantial.

Engines: The Heart of the W123
The diesel engines in the 200D, 240D, and 300D models – the four-cylinder OM616 and five-cylinder OM617 – are renowned for their durability, often lasting hundreds of thousands of miles with proper maintenance. While the 200D can feel underpowered, the 240D offers a better balance of performance and economy. The OM616 engine in the 240D is robust and reliable, requiring mainly regular oil changes to ensure longevity. A common weak point is the rear crankshaft seal, which can leak and cause oil starvation. However, parts for these engines are readily available, including budget-friendly options from suppliers of Force Tempo Traveller spares.

The 300D’s OM617 inline-five diesel engine, with turbocharged versions appearing post-1981, is another robust unit. Common leak areas include the cam cover, oil pan, and fuel-return lines. Inspect the injection system hoses for leaks; while replacement is straightforward, fuel leaks can indicate more significant issues. Some play in the accelerator and injection system linkage is normal, but excessive play needs closer inspection. The glow plug light should illuminate briefly (under 10 seconds). While diesel engines may produce some smoke, excessive white, black, or blue smoke signals potential problems. Oil changes should be performed at least every 8,000 kilometers to maintain engine health.

Transmissions: Manual and Automatic Options
Most W123s in certain markets were equipped with a 5-speed manual transmission. However, this gearbox is noted for being less refined compared to other Mercedes transmissions, described as somewhat “notchy.” Only models produced after 1981 received the 5-speed Getrag 717.4 gearbox; earlier models used a 4-speed transmission. Despite their less-than-smooth operation, these transmissions are exceptionally durable. Any unusual noises or vagueness could indicate high mileage and potentially neglected maintenance. The rest of the drivetrain is robust, although differential rebuilds and original equipment (OE) clutch kits can be costly. Using OE parts is always recommended for longevity and performance. The 4-speed automatic 722.1 transmission typically starts in second gear but will engage first gear under hard acceleration (kickdown) or when ‘L’ (Low) is selected. Differentials are generally reliable, but it’s wise to regularly check driveshaft seals as a preventative measure.

Suspension: Ride Comfort and Potential Issues
When evaluating a W123 Mercedes for sale, check for excessive play in the steering wheel. If adjustment is maxed out, a new steering box—an expensive repair—may be needed. Over-tightened steering boxes also wear out quickly, and often the steering damper arm is the actual culprit. The W123’s comfortable ride can mask worn shock absorbers, and coil springs can crack or sag over time. Noises from the axles may signal the need for replacement. Rear control arms are prone to rust where shocks mount, requiring extensive disassembly for repair. Rear wheel bearings require a specialized tool for replacement, making this a job best left to experienced mechanics rather than a DIY task.

Brakes: Servo-Assisted Discs
All W123 models feature servo-assisted disc brakes on all four wheels. This system is relatively straightforward and reliable. Caliper seizure is a potential issue, which can lead to a spongy brake pedal and reduced braking confidence. Master cylinder failures are also possible, but replacements are readily available and not overly expensive. Regular brake fluid changes (every two years) are essential to prevent moisture and air contamination in the system.
Examine the brake fluid reservoir and master cylinder for any signs of leaks, and check the brake fluid condition by removing the reservoir cap.
Electricals: Options and Reliability
While base-model W123s had minimal electrical equipment, higher-spec versions could include power windows, central locking, air conditioning, cassette players, and even electrically heated seats. Mercedes also offered options like automatic climate control and a Becker radio telephone – high-end features for the time. The central locking system is vacuum-operated and generally reliable when functioning correctly. Vacuum leaks can cause central locking malfunctions. Air conditioning systems may develop leaks and might still be running on R12 refrigerant rather than the more modern R134a. Test the power antenna for smooth and quiet operation, ensuring the mast is in good condition.
