This is stupid, but ... How do I upgrade or get a new car? Simple right? Help. Everyone is saying go to the shops and they'll help you. But I get there and..nothing changes. No door magically opens, so I try pressing start to see my options, nothing has changed there. Am I doing something wrong? The game said ni the messages that I could do it, but I just can't figure the stupid thing out. Help is appreciated. Thanks boys.
