In the trail run, I ran the MG and was matching Brad's Austin for lap times, although I did have a few spins in the MG.
I know when we did the trail at Morgan Park a couple of weeks ago I was just as quick in the MG (compared to the Austin Healey) but it does require a different driving style to the Austin. I think the MG was the easiest car to drive quick, however you do need to be very careful in the braking zones to avoid spinning.
