Please let us know where there is a '93 All-Trac for sale!!
Anyway, I own a 7th gen GT-S and a '92 All-Trac. I love both of them. They are two totally different machines. The 7th gen is light and agile.. VERY responsive!! The All-Trac feels like a boat, but it's fun going full throttle through corners and having grip when it's wet outside. In my opinion, the 7th gen has the better engine.. but the 3s-gte has a good track record behind it... but you are considering a GT, which has the
1zz-fe, so it seems to me that you are not looking for something fast.
If you want a car to modify, go with the All-Trac. If you want a comfy, reliable daily driver.. get the '04 GT. Put some wheels and coilovers on it and be done.
