Both cars also give you access to what is argueably the best farming race in the game; that being the Porsche Short Track Endurance. You have to fully upgrade as the race is in the Exclusive Series. You have to learn no assist driving and preferably Tilt B controls to do it, but then the skies the limit. After you master it, you can race as long as you want to. This makes maximum use of daily rewards like R$% and fame%. They pay the exact same fame/lap, the Porshce pays a pinch more R$/lap. You can see the info on their respective pages here Porshce ExclusiveAudi Exclusive.

I also made a teaching video using the Audi which I found a little slower and harder than the Porsche. This may help once you get one or both of them.
