Go for a petrol Saab 9-3 Sportwagon, which has far fewer complaints against it than the 1.9 diesel, whose swirl flaps, EGR, DPF and timing belt all give trouble and whose automatic can let coolant into the gearbox.
owners report 42.1 mpg, 87% of the official figure. Everything below is built from that data and the archived owner history, not from a press car.

Check a Saab 9-3 Sportwagon advert (free) →The petrol is the one to shortlist, because almost every warning about the Sportwagon, sold here from 2005 to 2011, is aimed at the 1.9 diesel. That's not a clean bill of health for the petrols, since there's very little on record about them either way. It just means the diesel's long list of failures doesn't apply.
If it has to be a diesel, make it a manual with receipts for its timing belt and water pump, because the automatic adds a gearbox risk the manual doesn't carry. Think about parts whichever you buy: Saab GB went under in November 2011, a 2019 report found rear suspension bushes for the 9-3 unavailable, and the CIM steering column module was already in short supply by 2013.
The 1.9 diesel is the one to approach with care, because it gathers more failures than anything else in the range. Its inlet manifold swirl flaps soot up and seize, and the flaps can snap off and get swallowed by the engine. EGR valves clog, DPFs choke, and oil pumps, alternators, dual mass flywheels and turbos have all failed on it.
The diesel automatic is riskier still. The heat exchanger inside the radiator can fail and send coolant into the transmission fluid, and once that happens the gearbox is ruined. A manual diesel avoids that particular problem, though it doesn't escape the engine's other faults.
The petrols have a much shorter charge sheet. The only engine complaint that could apply to them is a single report of failed throttle bodies on this Saab, and it doesn't say which engine. So you're picking the engine with fewer recorded problems, not one with a proven record.
On a 1.9 diesel, watch the exhaust and feel for power on the test drive. Smoke, or a sudden loss of pull, points to seized swirl flaps. Cleaning them doesn't stop it coming back, and the proper fix is a new inlet manifold, which takes around six hours because the fuel pump and timing belt have to come off first.
Ask for receipts for the last timing belt change and make sure the water pump and tensioner were replaced with it. One owner bought a 1.9 TiD convertible whose belt had been changed at 69,000 miles without a new pump; the pump seized seven months later, threw the belt and wrecked the engine. It isn't a one-off: seized pumps taking out belts come up on this diesel more than once.
Look for an ESP warning light on any Sportwagon. One report traces it to the CIM module on the steering column, which houses the steering angle sensor, and with ESP out of action the car fails its MOT. On a 1.9 diesel, ask whether the ECU has had the later software written to help the DPF cope with town driving, and on an automatic check the gearbox fluid for any trace of coolant.
