Flex this is such a personal preference question.
I've never been around the Nurburgring so I'd quite like to do that although I'm sure plenty of people who've done it will say that's a bit boring for your 40th. I'd also like to drive some proper supercars (Ferrari, McLaren etc) so that'd be something I'd love to do as well.
Personally I don't rate the whole "strip club" experience, ...I mean sure the women look amazing but it's like someone putting your favourite meal on the table, then rubbing it in your face so you can smell it but never letting you actually eat it.
Bl**dy frustrating if you ask me.
