i am actually buying a ta22 celica too (1971-1975) and i found it hard to find one that was straight, i was also looking for a fairly standard straight bodied little rust, that was manual and registered, soon enough i found that that would be too hard and i am looking more into just finding a nice bodied one, it'll probably be unregistered and without a motor, but all things that a little work and ALOT of money can handle. Good choice too, the ta22 models are sick!! Good luck in the search!
