You can't get the Titanium in a manual so it would have to be a Focus SE. Stupid Ford.
Golf Wagon TDI.
I'm not exactly sure what Brigitte's driving habits are, but considering her 11 year old still hasn't hit 200,000km, I don't think a TDI would be worth it. You need to drive long distances for a TDI to warm up and be as efficient as it can be. Plus, of course, the more you drive a TDI, the quicker you get your initial additional investment back.
