If you're okay with non-VAG options then it might be worth considering a Mondeo estate. I've got a 2L diesel and it gets over 50mpg normally, and seen over 60mpg on a motorway with the cruise set at 65.
Given the popularity of the Transporter I can't see the garage putting up too much of a fight (let us know). They command such unreasonable prices.
My mum has just bought a VW Transporter from a dealer. Last night it broke down at 1am on the A1 (coolant issues) and the RAC man said he would be concerned it was the head gasket. She didn't get home till 5am.Understandably some trust in the vehicle, which is a significant investment for her, has been shaken. My read is that since it's within 30 days of purchase, she is entitled to a refund under the 2015 Consumer Rights Act as the fault, whatever it is, would clearly have been present when she bought it 2 weeks ago.Is there anything else people would advise quoting at the dealer from their soapbox should she decide to go down that route?
