Hi JRGGINO,
Mines a 270 CDI avant estate. In the last 6 months ive had it, it's performed beautifully. On avg I get 42MPG (remember it's an estate!) on a long run and around 30 urban. If I am very careful, I have seen 47 on a long run. I'm sure I can coax it to do more, but happy with it for the mo. BTW, it's 177bhp, only 7 more than the facelifted 220 CDI's iirc. The only thing I regret not having is park assist, it is hugely helpful if youre going from a saloon to an estate (like me). Mine is also a 7 seater, handy if you have kids (reason why I went fo an e estate).
Mine is a 54 plate (registered 05), it has SBC (sensotronic brakes or brake by wire), this had a fault when I first had it, fixed under warranty, I also had a problem with the airbags, again fixed under warranty, both small issues, I was told would not have cost much to fix at an indie. Overall, very satisfied. Hope this helps with your search.
