I've had a reply back from Dino at Nurburgring Experience, seems like a nice chap, also sent me a list of their rental cars - I'm quite tempted to hire one of their Clio 197s out there and they dont require a 5k deposit upfront - unlike Hotel Nordschleifes cars!
If I do this I'll do it the proper way and go with Nurburgring Experience as I like the idea of being with an organised group! He has even promised me some (hot) sighting laps in his M3 which I'm looking forward to
There will also be a photographer with his group the entire weekend. Only cost for that is £30 for a DVD of ALL the pictures taken - bonus!
Just waiting on my mates to confirm their time off and will confirm asap.
