TVR Sagaris
Once upon a time, for around £40k, you could get a car that could top 185mph, do 0-60 in a little over 4 seconds, and after you've parked it outside the restaurant in the place vacated by the BMW Mini Cooper, you could brag that your car would destroy that a SLR around the track. And whilst I'm not certain that TVR ever campaigned this car in the GT Cup, it would not have been embarrassed if it was.
