I think people carry out these conversions because there isn't a car on the market that's like that and/or their really attached to the car and there isn't another car like the one their going to mod etc
I don't think anyone's done a sx celica to a gt4 celica conversion because it would cost alot more than a gt4 to carry out the conversion.
But like the integra that was a rear wheeler for drift, there wasn't a rear wheeler integra on the market, and the idea would make peoples jaw drop (in a good way). get me?
