all of the cars you have listed have the potential to cost you alot more than the zed would,
rx7s need engine rebuild to offen, gtos are renound for being very unreilable, supras are nice but costly, evos are expensive to run/ insure
thats all just my personal opinion of course.... but if I were to take a step backwards but still have something nice id go back to a 200sx s14a, pick up a really nice one for about £4-5k, not crazy on insurance and very capable of putting a smile on your face
