Which used Toyota Previa MPV should I buy?
There are only two engines: a 154bhp 2.4 petrol and 114bhp 2.0 turbodiesel. The petrol is cheaper of the two to buy, but you'll have to keep feeding it plenty of fuel, which soon eats into your saving. Most are hooked up to a four-speed automatic 'box, but this saps the engine's power. So, if you want the 2.4, sniff out one with a manual gearbox.
Overall, though, it's worth paying extra for the turbodiesel. It has stacks of the low-down muscle you need for everyday driving, and is ideal for lugging seven people around. It's also smooth, quiet and economical given the Previa's size.
