Genuine question. Where are you able to find the prices? I've been looking for pricing charts like the 0-60 website for a while now and haven't been able to find one. Price ranges really are a useful tool when comparing cars. As for mid '90s Japanese competitors, I'd be willing to throw the Celica in there against the Mustang too. They're all different kinds of cars, but they're all performance cars in similar price ranges,
Kind of all over the place i think MSN autos might work just kind of a pain to use. https://books.google.com/books?id=g-76CwAAQBAJ&pg=PA298&lpg=PA298&dq=1996mustangGToriginalprice&source=bl&ots=kaDO5UWxqO&sig=0fmDoP9Lskr4DdxofEwH80Upy_E&hl=en&sa=X&ved=0ahUKEwiKr-Ws9vvMAhVCwGMKHUNEBWM4FBDoAQgzMAQ#v=onepage&q=1996%20mustang%20GT%20original%20price&f=false For mustang prices MR2 http://www.iseecars.com/car/1995-toyota-mr2 240SX http://www.msn.com/en-us/autos/nissan/240-sx/1996/sd-AAbL9Q3
