Which used Peugeot 406 saloon should I buy?
Peugeot's diesels rate among the best and suit the 406 well. You can choose from a 1.9 turbo giving 90 or 110bhp, a 2.0 HDi that took its place, or a 2.2 HDi with 138bhp, sold from 2001. The 2.0 HDi is the one to have.
Otherwise, the petrol engines run from a 1.8 to a 2.0, plus a 2.0 turbo, with a 3.0 V6 at the top end. The 1.8 puffs a bit to pull this heavy car, but the 2.0 or 2.0 turbo are fine, while the 3.0 V6 makes the 406 purr along, but running costs will hit hard.
