I have to say that although I'm just in the early days of C-Max ownership - it compares favourably with the previous cars I've had:
Peugeot 206 SW 1.4HDi - Too cramped in the back
Megane Scenic - When it rained, I got 6" of water in the footwell. Handled like a rubber dingy.
Range Rover P38 V8 - 16mpg...
say no more!
Vauxhall Frontera 2.2i LWB - Too slow & thirsty & unwieldy
Alfa Romeo 156 Sportwagon - Used a litre of oil per 100 miles!
This is the car I feel most likely to hang on to for a while. It's got the useful space of the Scenic, the economy of the 206HDi, and almost the handling of the Alfa (or at least it will do if I lower it a bit and fit 18's!).
I'm amazed by the power of the little 1.6Tdci engine, as it feels more like a 2 litre to drive. Even last night, picking up my in-laws from Doncaster Airport, with 4 adults and 2 suitcases, it managed nearly 60mpg over the 120 mile journey. That'll do me nicely.
