1988 BMW M5
Yep, at least in the US, it was only available in black, with tan leather. The E28 M5 is the original M car, and has recently been trending upward in value much like the younger sibling E30 M3.
This one isn’t perfect, with a few dings and some worn leather, but it’s still stunning. The S38 engine breathes a bit better than stock, with a Dinan chip and a Supersprint exhaust, which should sound spectacular.
It’s on eBay in Connecticut with reserve not yet met.
