I’ve got a 2009 2.0 diesel zetec which is the most popular and IMO the sweetspot – I certainly wouldn’t go for the petrol.
In short, it’s been great. I’ve done about 40k miles in it including holiday trips, etc. The boot is huge, the cabin is spacious (I’m 6’5″) and comfortable. The worst thing I can think of is that the tyres are fairly expensive (£75-£125 each not sure why the variation but replacement costs for similar products seem to vary quite a lot) and wear fairly fast, particularly at the front.
Oh, it is fairly long with overhangs – if you can get one with parking sensors, I would (I didn’t).
I might get the estate if I was buying now mind, just for holidays with two young kids really though we managed to fit everything in ok last year and still found space for 60+ bottles of wine on the way back.
