That's quite a list Brian!
A remarkably short list from me - all purchased new apart from the two vintage Astons.
I'm not sure there's a worst or best, the Audi was pretty boring and the Ford GT pretty exciting. I didn't get on with the Morgan Roadster, but really get on with the +8. The Range Rover has been 100% reliable from new to 150,000 miles - but I don't drive it at the moment.
I feel sure I've forgotten a couple.
