I had a few races... the best was when an old c320 tried to race a friend of mine in his subaru outback who was behind me and he saw that my friend was driving crazy... keeping up with me, but he did not see me...

So he pulls up to my friends side and says race me... my friend points at me... that was a good one...

Raced an SL recently... as well... and a bmw 3 series coupe... don't know what engines either of them had as I did not get a chance to notice, but neither of em held on what's so ever...
