Saab 9-5 OG

Production Years: 1997 - 20105 Documented Faults

The Original Generation Saab 9-5 was the brand's flagship executive car, renowned for its supreme long-distance comfort, incredibly supportive seats, and potent turbocharged performance, especially in the Aero trims. In the UK, the estate versions are particularly sought after as rapid, practical family haulers that offer a left-field alternative to the Volvo V70 or BMW 5 Series. The B235 engine in early models is highly susceptible to oil starvation from sludge build-up, making meticulous service history paramount. A well-maintained 9-5 Aero is one of the best value "Q-cars" (sleepers) available, perfectly suiting drivers who cover high motorways miles.
