Well, I really should get rid of the 3.0i but because I paid £6500 for her and have since spent loads on various bits and bobs and mileage is only 40,000 I cannot bring myself to sell her for the sort of money that the older models are fetching and so, with use now at only a hundred or two miles a year, I will probably keep her forever!
I love my 35i and quite like the 'new' X6 though!
