Stock AE71 (4AC RWD early 80's Corolla) - between $1-2k
Stock AE86 (4AC RWD early 80's Corolla) - between $4-5k
Buy the AE71 and spend extra $2k you saved on mods. Now car goes faster...
Buy the AE86 and you have a rare future classic...
Either way both good value IMO but if ur going to use it for track work or drift and want bang for your buck then can't go past AE71. Cheap and plentiful parts and essentially the same car.
