Hello again S.S.!!
Yep, those wheel marts are plentiful down there since there is less crime. Just go in, put your favorite rim in a cart and buy it. I gotta ask my cousin if he can show me where all the Sti shops and third party shops are!!
Oh yeah! The advanced Gran Turismo cars are taken from pictures of actual JTCC cars. The Castrol Supra, Cusco Impreza, etc..
