Like my topic, I do all steps by the readme that cars contained, like rewrite lines in Default.ide, Handling.cfg, etc. 
But every time when I installed a car, and run the game, I got an error when that car appears on the screen. 
Why? Can somebody help me? Really like those cars  Great thanks for reply !
