Someone I know just picked up a Civic from the dealer for around $15,000 after taxes, fees, etc. It's probably fine for them, but if I were in their position, I'd go a different route. Your objective on this hunt is to find a semi-reliable daily driver for no more than $15,000 that had a reasonable impact on automotive history.

My pick would be this awesome Buick Grand National on ebay for $15,000. Funny enough, it was the fastest production car in 1987.
