Not too long ago you could buy a hot rod track/auto cross car for about 4 or 5 K. I know because I bought two and sold both for a modest profit. My 16 year old son would like a track car and I am having troubled finding something well set up for for track duty for a reasonable price. Lots of project cars available for cheap but a decent driver is getting to be $$$.
We currently have a 71 with a 2.4 four that is a sunny day driver
We also a 70 track car with a 3.2
