every car has its flaws. I have read about a lot of problems with GA's on this site but ive personally never experienced anything major with my GA. My point: Even if Celicas have a lot of problems doesnt mean that urs will. Just get as much info on it as you possibly can then make ur decision from there. And like grfnkl said, check forums on it and see if there are many reoccuring problems.
Personally id stick with the GA..but thats cuz im a proud owner of one
