alright heres my input, and the honest one.
del sol - you love the car go for it
240 - played out as bad as a civic
300zx, yeah its an awesome car, but not worth it. if something goes wrong, your ****ed, those things are impossible to work on, also insurance will eat your balls.
lude-good car, my friend has a 94 si

all in all, go for another sol...or you could get an S, and hop a b18c or c5 in there
