I own two third generation Celicas, a 1982 and 1985 both GTs. I bought the '82 early last year and the '85 later in the year. The '85 was driven daily and is in great mechanic condition and even has a functioning A/C. I've only replaced the shocks and struts so far. There is are some rust spots on the '85 and considerable cancer on the left fender. Being the '85 is in the better condition. I used the fender from the '82 to repair it.
Fender comparison; notice the rusted out areas on the bottom fender and it looked worse from the underside; there are small differences between them, but very minor
After the swap
I will be freshening up the suspension soon. More pictures to come soon (I hope).
