Which used Ford S-Max MPV should I buy?
From the three petrol and three diesel engines available, you're best sticking to the 138bhp 2.0-litre diesel. The 1.8-litre diesel is slightly more economical, but isn't always up to hauling the S-Max when fully laden. There is a less powerful version of the 2.0-litre diesel (127bhp), which is an acceptable alternative, and a 2.2-litre engine with an impressive 173bhp.
Both the 2.0- and 2.3-litre petrol engines are smooth, but the fuel economy may put you off. The 2.5-litre turbocharged engine is fast, but even less economical. An automatic gearbox is available with the 2.3-litre petrol model and 127bhp 2.0-litre diesel models (137bhp from May 2008), but it does hurt economy further.
