For those having problems, give this a read and you should be fine. When you first upgrade the car, DO NOT SELL IT RIGHT AWAY. Go to the store. Pause and push L1 X X. You then back out and will be back with the bike. From here you can go to Los Santos Customs and sell it over and over again. Enjoy the glitch!
