Ive driven one, several times. Took it for about a 18 mile round trip through twisty A roads in the wet on one occasion. Nearly went side-on into a van when overtaking it due to torque steer. Horrendous in the wet. Really hard to keep the thing going in a straight line, and for your average driver (like me!) hard to drive quick and smooth. Shedloads of grip in the dry though, little body roll either. Fast, with brakes to more than match speed. Gear change is awesome, short and sweet, leagues above the Clio IMHO. Seats were brill, as is the push button start.
For what its worth, I think they look nice too.
I dont want to start a Vs thread, and Im sure a Cup owner will argue, but IMHO ( and Ive driven all three -172, Cup, FRS and been involved in some, ahem, battles against a FRS) the FRS is definitely the quickest of the three.
My mates FRS leaves my 172 standing as the speeds get higher, although there is not that much (IMHO) between a Cup and FRS off the mark, but I think thats more to do with traction than anything else..
