if you want something cool and cheap get a Kei car from japan, buy one at an auction, and you can easily have a cool car landed for 3000, I have had three cars imported from japan and all have been great fun, this is how much I paid for the, landed in Canada
1990 RX7 5000$
1994 Celica GT Four WRC edition (2500 made world wide) 13 500$
1992 Mr2 4000$
all of these were in perfect shape when I got them, the GT four only had 20 000km on it, you can get a cool and interesting car from japan for less than 3 grand if you look hard enough, although I am not sure about the United states' import export laws
