What exactly are you going to use it for? depends on that question first to be honest. although if i was to throw a good, cheap, fun project car out there, and this is just me though, id say a mx5 na6/na8. reason being the parts are dirt cheap and having SO much aftermarket parts for it, you have endless supplys if anything goes wrong (like more project cars do). they handle amazing which is sad as they are always mis-titled by people that never actually try driving one. and best part, there is so many of them out there for you to choose from so shouldnt have issues finding one especially in the US. from stock they are definitely slow but easy bolt ons can definitely already put a smile back on your face.
