Let me explain what i have on this car. I just installed a video player inside with 7" inches wide screen. I can watch movies, TV, karaoke, front and back view. i also changed shocks and springs, the shocks are adjustable in the height. The engine is a normal 525i but i am about putting a 2JZ VVTTI toyota engine 2.8 twin turbo intercooler in. But that's just under progress. Hasan from Thailand [email protected]
