I've owned 3 5th generation Celica's over the years ranging from a 1990 ST to a 93 GT-S. My GT-S has 257,700 mile on the original motor. The original transmission and original clutch had to be replaced at 243,000 miles. Fuel mileage isn't great, 22-26 mile per gallon, but the ST model with the 1.6 liter gives nearly 40+ on a trip. I plan to keep the GT-S until she dies.
Engine, body style, interior, finish, and last for ever
