The 2.0 TDCi Titanium would also be my choice. I ended up buying a Zetec as I couldn't find a Tit at the right mileage/price combo and I've regretted it ever since. The Zetec is poverty spec in comparison, and what "goodies" are included, namely sun blinds, "privacy glass" and a kiddy spy mirror are all but useless to anyone without youngsters! It's the only car I've ever had (with lecky windows) that doesn't have "one shot" up on the drivers side. It'll go down, but not up. Inexcusable in this day & age!
I would always go for the 2.0 over the 1.6 or 1.8, if only because the 6 speed 'box on the 2.0 is MUCH nicer to use than the 5 speeder on the other two. Driven with a modicum of restraint, the 2.0 is not much heavier to run. My usual MPG, up here in Shetland is about 47/48 worked out the old way, with a best over a tankfull of 51.5. Not bad for a vehicle which will sail effortlessly up every hill it comes to in 6th and goes like stink if you want it to!
