1971 Mercedes-Benz 300 SEL 6.3 (W109) RHD

The W109 300 SEL 6.3 (1968-1972) used the M100 6.3-litre V8 from the 600 with 250hp. The original super-saloon. Discreet looks with devastating performance. Now highly collectible.

Engine: M108/M130 six reliable. M116 V8 robust. M100 6.3 needs specialist knowledge. Body: Rust is the critical issue - check floor, sills, inner wings, wheel arches. Suspension: Air suspension on W109 - check operation and leaks. Vacuum systems: Age-related issues. General: Robust but rust is main concern.
