    Cars - Private Party
    Due to an unfortunate turn of recent events, I'm forced to sell my E28. This car is a result of a 6-month build involving 4 different cars. It drives nice and tight, sounds incredible, and has real presence. E28s aren't common sights on the road, let alone a clean euro-bumpered one. 1985 BMW...
