you could quite easily get a decent 7 clone at that money but it will most likely have a older engine such as a pinto or crossflow or something newer but not much used.
tbh they still go really well with even a mild tuned pinto and you could always upgrade the engine at a later date.

i would try a few out for size the original locost book plan built cars are very tight for people over 6FT and with wide hips

hoping mine will hit the road very soon after 18 months of tinkering they really are the project that's never finished
