The Hot Wheels track is pretty cool. However, it makes it hard to move from point to point if you don't have fast travel unlocked. It's also pretty repetitive and the Hot Wheels cars themselves aren't all that great. You also never race against other Hot Wheels cars, just the normal Forza cars. You're doing all the same things as you do in normal mode but on the new track. All in all it's not worth the asking price, get it cheap on a sale.
