You can usualy get some mid 70's detroit BEHEMOTH for cheap (Impalla, Cordoba, LTD, etc...) I had one as a winter beater during my college years (.76 Impalla with a 350) The freeking thing was 18.5 FEET LONG from bumper to bumper (longer than my parent's conversion van!!!) The hood was big enough for 7 of my friends and I to lounge on at the local drive-in
For style - add some glass chandeliers on the front fender corners (ala Isaac Hayes "the Duke of NY" from Escape from NY) and you'll have a Ghetto Cruisin' HOOPTY!!!!!
