A friend over here in SW France (80 years young) built and races his MGTC - now supercharged - at a number of venues across the region. His car is very, very quick but his nemesis is his friend in an Ulster which, although he is faster on the straights, he just can't match on the twisty stuff.
He's currently reworking the suspension but admits it won't make enough difference and he's resigned to second places again this season. Those Ulsters do seem to be a bit handy.
There's a little 1928 Frazer Nash saloon that normally does pretty well at Goodwood, racing against much more exotic machinery of the era.
