salam,
I would like to reply both.It is not GT-4. Its 1.6 liter twin cam 4AGE engine an economy model for celica.
The answer to second reply is that whole car is in its original color that is white and what you see red on the car is a body kit as normally that kit costs about 3000$ if you buy it from the toyota company.But last time when i was in switzerland i found a red color GT-4 celica 1988 with this body kit.I brought that car to czech republic,prague where i lives and seperated the kit sold the car there and brought the kit here in pakistan for this car.I think you feel crazy but this car was imported from japan in 1988 here in pakistan and is my first love. thanks,
nadeem.
