I've done well out of the big C4, sadly I've had enough of them now. They are made of glass and for me are no longer worth the hassle, especially with the new SOGA coming out, I've got zero faith in them. I've never had much of issue with the CDTI120 BHP Zafira. As for the petrol, whilst customers are a pain in the arse, nobody is that bad that they deserve to buy a 1.6 Zafira.
