Looking through ebay at cars, and I have to ask, why do modern minis go for so bloody much? Found one with a massive scratch on the side, tatty condition and it's going for over £1000. I'm talking about the modern minis from the year 2000 upwards.
As GiantKiwi said though, they are in fact BMWs so they have BMW prices. Spares are also BMW prices so beware anyone that fancies a 2nd hand one. Also - only buy the 2008 models or later. They sorted out most of the issues on that model.
Yeah, the cabin space is pretty bad. If you look at them from behind you can see that a lot of the apparent size is in the arches and door panels. Once you go above the window line it gets a lot narrower!
