Maybe it's a badging difference. I'm not aware that Saab ever made a 9-5 convertible, certainly not for the UK market, just a saloon and estate model. Pretty sure the one in the picture is known here as a 9-3, and is based on GM's Vectra platform. Either way, a nice looking motor
Saab was always a marginal brand here. The only Chevy based 9-3 I remember in the US was a sedan. There was a 9-3 convertible made, but I don't recall seeing one here. it didn't look like the car Burt posted. That looks like a 9-5, although the front and rear are cut off.
But, like I said, Saab was never really successful in the US, so I don't know as much as I would, normally. The 9-3 Chevy/Saab was a disaster in the US. Saab is now a military supplier for the US military. No cars.
