I love this car - my third Saab. Bot it used in Jan 09. Drive 3 times a year from Maine to western PA (about 850 mi).
Always have used regular gasoline and my highway mileage is
consistently 36.5 mpg. I drive about
9 over speed limit and occasionally high 80's.
The car goes great, climbs the PA mountains with ease at any speed, accelerates on demand, and is wicked fun to drive. In town mileage averages 25. Not sure why my mileage is so much better than what others report except that I am driving a 6 spd manual and I'm apparently driving it very well:)
I am so sad that Saab is no longer. It delivers great bang for your buck! My 99 9-5 with 190k is used daily for commuting by my daughter
