Which used Citroën Grand C4 Picasso MPV should I buy?
A diesel engine makes the most sense in a car of this size, due to their economy and pulling power. We find that the 108bhp 1.6-litre diesel suits the car best because the 138bhp 2.0 version isn’t vastly better. If you want a petrol-powered Grand C4 Picasso, then choose between the 1.8- and 2.0-litre engines. We'd go for the former because it's not much slower than the latter.
Stretch your budget, if possible, and avoid the entry-level LX model. It's sparsely equipped and doesn't even have air-con. The SX is a much better bet, but the VTR+ gets alloy wheels and rear electric windows and therefore looks a lot smarter. The Exclusive has climate control and parking sensors but isn’t necessarily worth the extra cost.
