Had a go in a Hummer H3. It felt like a lorry and was a powerful beast, but I wouldn't say I enjoyed it. I was just helping out a mate at a car show and he needed drivers so I thought I'd give it a go. Wish I'd chosen the Skyline though, I think I would have had a lot more fun in that.
Does a 25 foot limo count? It was a job I had for a few months but I got fed up with the sort of people we were picking up. Drunken party goers, hen nights, and stag do - people who have no money or manners acting like spoilt rich people.
I got out of that job as soon as I could. Don't recommend it.
