Horrible! I used to like it, but developers changed the matching criteria, making it impossible to advance if you're not willing to spend a lot of money. You can still play if you don't care about not having a slighty chance in the GPs every weekend, regardless of playing every day to build up your parts and drivers. I have spent money, but it's not enough for them, anything less than $100 won't take you anywhere. So, if you don't want to spend a fortune, look elsewhere, don't download this.
