Strangely enough I don't get that many comments, I do however often return to the car to find people looking at it or taking pictures, and also see them doing it when I'm in the garage paying for a fill up. Normally when they see that I own the car they sneak off embarrassed. It got a fair bit of attention at the Nurburgring as well, a lot more than all the hundreds of Porsches and race spec BMW's anyway.
Also when I show people how well it goes they don't tend to say anything, even if I ask them questions they often don't reply, just sit there clenching their buttocks and holding on tight to the door handle to control their shaking......
