Which used Peugeot 607 saloon should I buy?
At launch in 2000, there were three engines, 160bhp 2.2-litre and 204bhp 3.0-litre V6 (upgraded to 211bhp in December 2004) petrols, as well as an 136bhp 2.2-litre diesel. A 2.0 110bhp diesel and a 2.0 138bhp petrol were added in 2001, and your best bet is to buy any one of the diesels, although the 110bhp version is a bit weedy.
There was a very minor face-lift at the end of 2004, and the range was simplified a year later to just a 2.0-litre 136bhp diesel and the 3.0-litre petrol. A 2.2-litre 170bhp diesel was added in 2006.
