My sister is on her second now, she bought one new about 5 years ago and bought another new one last year (opted for the diesel version this time) she said the fuel economy isn't as great as she thought.
When we've had them in FLorida my husband found a couple of nasty blind spots but put it down to being longer in teh body than my sister and therefore looking from a different angle but my nieces husband bought one at the weekend and said he's noticed a couple of blind spots where the seat belt goes as the chassis is quite thick there (he said it does force you to look properly over your shoulder rather than just a quick glance as most do so maybe thats not such a bad thing. They have found it quite heavy on petrol, though.
