I just bought a 95 celica. I believe it is an ST, but the original owner bought the car straight from the manufacture. He got pretty much all the options that the GT models have, which leaves me to beileve he may have gotten the 2.2 liter. If anyone knows where I can help me out that would be appreciated >>

Pop your hood, and look in your engine bay. If your engine looks like the one in the following photo, then you have a ST.



If it looks like the following image, then you have a GT.
