A couple things that are holding me back right now...
How does one obtain a Nascar? I've completed the Jeff Gordon Nascar challenges, but only won with bronzes and didn't get a car
Do I need to go for silver?
How did you guys win your first race cars? I can't complete Like The Wind in A-Spec with a Veyron because there are turns, lol.
I also saw something in another thread about using a '69 Camaro (coverted to a race car) or a fully modded Countach to win the Historic Race Car series. I'll have to try that
One tip that I can offer is to complete the GT All-Stars series (the second to last in the Expert races), I used the '07 Mazda Furai Concept fully modded. This car was won in B-Spec in the Mazda Miata race series. The competition has 600-800+ HP and the Mazda only has 570hp but it only weighs 675kg
and takes any of those cars in the twisties
