Feel for you mate, let a friend drive mine and he got a bit cocky and lost it. Luckily it was in an open car park and from this day forward no one gets near the drivers seat.
Shame you weren't so lucky, but the main thing is you walked out of that unharmed, and you've got a top mate and wife to see you through it.
Not only that, looking at the spirit of the forums in the previous posts, makes it a pleasure to be part of this community
