Which used Citroën Xsara Picasso MPV should I buy?
Pick any diesel - they're all good. The 90bhp 2.0 HDI is strong and there are two even better 1.6 HDI diesels (92bhp and 110bhp). All are easy on the juice, pull smoothly and are reasonably quiet. We'd be happy with any of them.
If you're on a petrol-only diet, though, go for the 1.8. It's much livelier than the 1.6 petrol, which can feel sluggish when the car's fully loaded. The 1.8 is also much quieter - the 1.6 can get a bit loud when you start to work it hard. There's also a 2.0 petrol with a four-speed auto gearbox, but it's a disappointing combination.
