The Saab 9-5 is a keenly-priced, well-equipped alternative to the Audi A6. Up to three years old, values drop more rapidly than other executive models, so private buyers can pick up real bargains.

A 99T 2.0t with 50,000 miles is just £8500 from a private seller. More desirable still is the 9-5 2.3 SE with CD player and climate control.

A 99V 35,000-miler is about £12k at an independent. The range-topping 3.0t V6 Griffin can be as little as £16k for a 99T with 30,000 miles at a Saab agent (list price was £33k).
