Absolutly stunning car, have admired them for years. Rumor has it that Mc Clarren used them to test the F1 road car engine during development.
Always wanted one until I had a chance to sit in one at B M Motorsport Aylesbury a couple of months back. What put me of one as an every day road car is that because of the high sill and the low roll cage they are very difficult to get in an out, more like climbing through a port hole. Although aging a bit I am medium build and relatively fit and there was no dignity to getting in and out. They really are a road legal race car. Still would like one as a toy though for Sundays, fun days and play days.
Pound for pound there is nothing else road legal to touch them for performance.
They also hold the record for 0-100mph-0 in 9.4 seconds
