Well our son thoroughly enjoyed the experience and was marked 37 out of 40 for each drive - not bad eh since it's not even a year since he passed his driving test!!! He did find it hard to "put his foot down" but managed 111mph in the Aston Martin. I thought he'd prefer the Ferrari but he in fact preferred the Aston Martin.
If you are stuck for a present for man or a lady (something like this doesn't appeal to me at all but there were quite a few ladies going for the driving experience) it's certainly something to think about and I'm certainly glad we picked it as I think we would get 20 out of 10 for picking this present for his 18th birthday back in August!!!
