I've driven a few of the 88-91 Corolla GTS'. They handle very well, very neutral and with good rubber and driving they don't understeer at all, but they're not meant to be drag cars, so don't expect to win every stoplight to stoplight run. Parts are dirt cheap and so are the cars. They use two different versions of the 1.6L 4AGE engine that was found in the earlier RWD GTS. The first is found in the 88-89 model and has a TVIS badge on the intake manifold, that motor is rated at around 115HP, the later motors are of a higher compression and are rated at 130HP, they don't have the TVIS badge. Avoid the SR5 at all costs, different engine/tranny/suspension/interior. I'd tell your buddy to go drive one.
