1975 Mercedes-Benz 450SL Convertible

In terms of longevity, the W107 SL series outlasted all others, remaining in production from 1971 until 1989 and was known to Stuttgart's own designers as Der Panzerwagen due to the massive construction and vault-like build quality. With sophisticated new suspension featuring semi-trailing arms at the rear replacing the notorious swing axles of previous SLs, along with coil springs and telescopic shock absorbers with the option of an anti-roll bar and limited-slip diff along with disc brakes and power steering.

Launched initially in 280 SL (six-cylinder) or 350 SL (V8) form, the latter was joined by the more powerful 450 SL in 1973 with 225bhp and anti-squat rear suspension to cope with the extra torque. With hewn-from-solid styling, a beautifully appointed and functional interior and the option of a hardtop to create a weatherproof coupe, the W107 SL was a versatile and accomplished sports cruiser.

Boasting effortless performance, largely bullet proof mechanicals and unrivalled safety features, the 450 SL remains a great choice as an eminently useable classic roadster today.
