The Mercedes-Benz W114 and W115, known as the /8 (Strich Acht), were the brand's mid-size models from 1968 to 1976. Designed by Paul Bracq, these cars set new standards for safety and ride quality with their advanced semi-trailing arm rear suspension. W114 models featured inline-6 engines, while the W115 line used durable 4-cylinder gasoline and diesel powerplants, which earned them a reputation for being nearly indestructible.
Collectors are drawn to the /8's clean styling, legendary build quality, and straightforward mechanicals. The pillarless coupe (C/CE) models are especially desirable for their elegant looks. For many, these cars represent peak Mercedes-Benz engineering from an era when longevity was paramount. They offer an accessible entry into classic car ownership without the complexity of later models.
The market for the W114/W115 is diverse. While driver-quality sedans remain very affordable, pristine, low-mileage coupes and top-spec 280E sedans command significantly higher prices. With an average sale price of just under $14,000, these cars offer a lot of classic style and durability for the money.
Buying Tips
- Rust is the biggest enemy. Check the rocker panels, floor pans, jack points, and around the front and rear window seals.
- The vacuum system controls the door locks and climate control. Leaks are common and can be frustrating to diagnose.
- Diesel models are famously robust but slow. Check for difficult cold starts or excessive smoke, which can point to glow plug or injector issues.
- Inspect all rubber seals and suspension bushings. After 50 years, most will be dried out and cracked, leading to leaks and a noisy ride.
- On gasoline models, ensure the carburetors or fuel injection systems provide a smooth idle and acceleration, as repairs can be costly.
Prices range from $720 for project cars to $48,000 for exceptional examples.
