The best one for me was the Toyota GT86... But if you want a good result I would use the Lambo Miura (Premium) or any car which is heavy but has many HP
NSX. Mine wins by a lap and a half I think? been a while since I last did it but I know my driver didn't have the slightest bit of trouble.
I usually farm the autumn ring race for money so yeah.
If you're willing to spend a bit of money, i used the GTR Proto 2005. It has great grip for B-Spec so your driver won't spin out.
You should use the 'Edit' button to avoid double or triple-posting. Alternatively, if you need to select multiple quotes there is a feature for that too (the two little speech-bubbles next to 'Quote'). 👍
On topic: the NSX should win any 500PP races with relative ease.

Honda NSX Type R '02 or Lotus Elise 111R '04. Both will win that race easily with a driver of a reasonable level (not 0). Don't need tunes either, but you could put a basic tune on them if you feel it'll help. The NSX can win all the 500PP races without any fuss at stock PP in A-Spec and if you just add parts to get it to 500PP it will not have any trouble in B-Spec too.
