Vehicle Details
AI Listing Summary
This 1991 Mercedes-Benz 300 SL is a rare Smoky Silver model with only 89,548 miles, featuring the desirable 24-valve M104 engine and a rare color. It comes with a hardtop and has a generally solid exterior and interior, though it requires some minor cosmetic and mechanical attention, including non-operational wipers and a driver's seat issue.
Condition
7
The car has a rare Smoky Silver paint, which appears gold, and the seller is a reputable designer. The exterior has a nice shine with straight panels, but there are some cosmetic flaws including stone chips, scratches on the door trim and rear wing, peeling paint on the sill, and rust spots on the headlamp reflectors. The black fabric roof shows minor wear with a few small holes and eased stitching, and the inner headlining is grubby with slight damage. The hardtop is in good condition. The 16-inch alloy wheels have light, touched-up nibbles. Mechanically, the engine runs well, but the air ducting has been repaired with gaffer tape, strut top bushes have perished, and the wipers do not operate. The driver's seat only moves backward, and the ignition switch needs attention.

Description
Offered until 1993, the 300SL-24 is powered by the 24-valve M104 inline-six petrol engine that offers the driver 228bhp and 200ft.lbs of torque, enough to see the car hit 62mph in 8.4 seconds on its way to a top speed of 149mph.
Classics World suggests its presence should make this one worth an extra £1,000 compared to a similar model without the benefit of this engine, and no lesser classic car authority than Vicky Parrott owns one, which tells you all you need to know about how well they drive.
‘SUI 1566’ is finished in Smoky Silver, paint code 702, a colour so rare the seller has only ever seen three and he notices this kind of thing because he’s a multi award-winning creative director and artist who’s worked with firms such as Jaguar, Ferrari, and Aston Martin; if you remember the matt-white Morning Frost Vantage from its launch, then you’ll have admired his work too.
He’s also been exhibited in the Museum of Modern Art in New York, been named GQ’s Most Stylish Man, and awarded ...
