I think it looks too cheesy and not right. For one we have no use for cars. If more detail was put in e.g Road tiles, Decent looking cars which you and another player could both get in like a group session of some sort and go places, Upgradable parts ect. It would make them worth having, But no its nothing like this its jus UCDIYs little way to try make more money :P
