I'm unsure about track days, I've done one in my M Roadster at Brands Hatch with instruction and to be honest it didn't float my boat.
I consider myself a capable driver but does that mean I'm a 'track day driver' or would I just be going faster and hanging on for dear life ?
Just a note, the guy I bought my CSL from is an extremely capable driver and he said that the capabilities of the CSL exceeded his capabilities
I often wonder if the driver that does a few track days a year isn't just another nutter that thinks he knows it all behind the wheel (#runs for cover)
