Many users started to face the problem with their elite vehicles – Sultan RS and Banshee. The problem is when you try to upgrade your car with really expensive tuning (from 100.000 to 3.000.000 GTA$) everything OK until you restart the game and all upgrade are gone. Some classical upgrades remain on its places but customized interior, headlight covers, roof scoop and my other details are just gone. If you want to rebuy all this stuff again with reinvesting your own money the same thing happens.
