1987 Maserati Biturbo
Really, this has to be better than the contemporary E30 M3. 40 more horsepower in a similarly-sized package, but with Italian style rather than Teutonic restraint? That interior is elegant and luxurious. It’s half the price of a comparable M3, too.
Honestly, though, this is probably top of the market for a Biturbo, though it looks to be one of the best available. One owner, 24k on the odometer..though one could assume much of the time parked was in or near a service bay.
It’s on eBay in Los Angeles for $17,500.
