Hey Dave,
Sounds like the sort of knob I'd expect to drive a VXR! ;)
Had a bog standard Carerra up my bum on the M25 this morning. Given we were on the camera section before the Dartford Crossing, decided to move to the middle lane and let him past. Sure enough, he passes me at around 90, then slows down for the 50 bit (still 60 mind).
I picked a better toll booth than he did, and we ended up level at the barriers! ;)
I chucked on the Apexi throttle controller(red mode), put it in Sport, and floored it. The chaps face was a picture! Must have made six car lengths on him before I slowed down. Had a face like a bulldog licking pee when he finally passed me!! ;)
Such a good all-rounder the IS-F. :)
Love mine!!!
