Looking for some advice, please. I'm thinking of downsizing my petrol car to a smaller diesel. Reliability is really important, as are running costs, after that as much spec as I can get bang for my buck! I've looked (on paper) on the 4 above so far but before I hit the forecourts I'd really appreciate any feedback on any of these cars, or if anyone has any other suggestions I should be looking at? I'm hoping to pick up an 11/12 reg and holding it for a few years so want to get this right! Thanks
