Birthday driving experience

[MrsH11]

Hi
It's my husband's 40th birthday soon and I want to book him a driving experience. I'm thinking supercars, race track, plenty of driving time. We are based in East Anglia. I keep reading reviews where it turns out the cars have been limited or you're not allowed to drive them flat out - definately want to avoid that!! Around the £200 mark - any recommendations????

Thanks for the ideas and hints - much appreciated!! Want to make it memorable and I suspect it's going to open the flood gates for him wanting to do more probably want to have a go myself!
