I don't care about the depreciation, or the extra maintenance expense occured due to driving it every day. In fact I'd be happy if I could drive it any time I need to move from point A to B.

It's the idea of not being able to get to places that other cars can (over speed bumps, steep car parks, narrow passage ways, etc) that does annoy me. I don't like having to plan my route beforehand. That's why I'm asking for feedback from Londoners who have driven it round quite a bit...

Alternatives:

Ferrari F430, Audi R8 (neither are more practical though are they?)
High-end Porsche (not exotic enough for my taste)

That's all I can think of in the £80-£120K range! Ideally I only want to purchase one car, as opposed to exotic + every day car.
