My 2000 Celica GT-S is the best car I have ever owned. No major mechanical problems. Looks great, sips fuel, and is fun to drive. It's getting older now with 140k miles on it, but I can't find an excuse to get rid of it. Just a great car.
Minimal upkeep, very fuel efficient. When the weather and driving conditions are right, I will see 400 miles on a tank. Having the 6 speed manual helps.
Original tires wore out too quickly, find another brand suitable for your driving conditions. Road noise is noticeable with higher performance tires...maybe not at first, but as they wear it will get louder in the cabin.
