Well after owning this game for about 9 months, i've finally managed to get it working online! I had that issue with teredo and gave up trying to fix it. I decided to try and fix it once and for all last week and for some reason it just connected straight away, must be to do with the latest windows 10 update? Anyway, can finally start playing at last. Firs thing i've noticed is there doesn't seem to be any structure to buy better cars as you progress, you can literally win them all on the wheel spins! I've bought a few from the auctions too. Loving the Mclaren Senna the most at the moment, it handles great in my current tune.
