Runs such as his 185+mph runs at Brunters etc etc.

He counted 7 memorable days. The rest it was largely off the road broken.
His car stood him at £30K.

I asked him if i was to offer him a drive of my car that would do 185mph today, would he accept that drive and be willing to pay £4285inc vat for it as thats what every momorable run had cost him in his?

Sadly, thats the reality of these cars and its a rich man who can just keep on going. He sold the car that weekend and bought a 911.

I havent seen him since. More fool me.
