I have a list of over 200 cars owned, really, used to sell semi interesting borderline cheap classics from my house as part time trader. It's been a blast and I have owned many interesting cars. I always feel there is a difference between best and favourite. My favourite cars from my list have been my first 1200cc beetle and my first cinquento sporting, that from a list that includes Porsche, jaguar, BMW and merc. !
