How much money do you have to spend a good condition low mileage 94 is gonna cost you around 20K or more. I have an mr2 that is modded and I can tell you unless you know the car and how to work on it dont buy one. I love both of them but it can be a pain owning them. Everything is expensive everything is hard to install (perf or mainten). But They are fun cars and can be a mid 13 sec car with mods under 1000 bucks. Mid 13sec car and can out turn alot of the cars on the street. What more can you ask for... If you do find a 94 (kinda doubt it very hard to find) keep it stock when you own it youll know why.
