Yep, did Bedford last year, and it was fantastic. Drove the Formula Palmer Audi there amongst others, but the scariest was being taken round the track in a Clio 172 that had been stripped of all weight and I was sick in the car was that hairy!
They've replaced a few cars since last year, believe they have the Porsch 911s there now.
I did one of the track days at Brands Hatch a few years ago, and they don't ket you push the cars as hard as at Bedford. Look out for Jonathan Palmer landing in his helicopter, he did the day we were there to say hello in the mornign to all the groups, and then flew off to Brands Hatch.
You will enjoy it, we didn't pay for it, and have managed to get a supplier to pay again in June. Well looking forward to it!
