so this is my thought:
toyota ts020 at watkins
around 20 laps
I tested the car in practise mode, did 6 laps and my best was 59:85 so it would be a nice and quick race.
of course loads of people can beat this time
(the car was bugged I know, if you reinstall the latest built over the game there will be no temp car problem this version would be: simracewayGame_88.exe)
