328i 4 door for $6k. Springs & shocks, wheels & tires, M3 cams and valvetrain...another $5-6k or so for a GT35R turbo setup installed and you got a reliable 500+whp 4 door that will run circles around just about any sportscar under $75,000...in a sedan - http://atlanta.craigslist.org/car/589698337.html
