I'm at level 250 and I do a 10L lemans few times, and ferrari 4-lap once with the blonde babe(i.e. agent). Then use 1)Endurance in scuderia(high F/min) 2)Accolade open 18.3-melbourne- 4000 fame 3)Imp:Accolade Open 1.1 - Autocross melboune - (500 fame in 30 sec) 2-3 times and

I'd do a cloud save and repeat the 3rd race untill I feel it's less than 1000 or do a restore after level up.(you could do 1st and races 2nd races multiple times depending on your requirement)

One more thing.. you don't need to get as close as 1000 fame all the time, depending on the next bonus event, getting close enough for a level up from that event is enough. I'm sure you already figured it out.
