I've been having a lot of problems too. Baron's trick of disabling the media server connection may have helped a little, but this game is still so awful. I had wondered about the number or cars too, but one of my accounts has only 67 cars and is just as bad. Some of it may be the router and needing to set up a DMZ. Unfortunately that's above my pay grade. I think a lot of my problem is my PS3 and internet. I'm figuring there is a corrupt data issue, or a worn out system. I have a brand new PS3 here now, and super speed internet is coming at the end of the month. When those are up and running, I'll know that if I'm having problems at least its not me.
