Greg, There have been a huge number of Saabs produced in 43rd scale as kits (mostly as competition cars) and quality and affordable handbuilt road cars. Somerville (Billinghay, England) produced a whole range of them. I am looking at their advertisment in a old issue of Model Auto Review which lists 92's, the Sonett, a 95 estate, several in the 9000 series including the CS, CD, Turbo 16, cabriolet and even a Belgian police car. Rob Eddie also produced Saab's in 43rd, Brooklin is another producer worth checking out.
I know people are these days preferring 1/18th diecast but the world of 43rd is massive, gigantic, huge (get the picture!) with a range that outdoes 1/18th by a factor of a zillion. The quality of Brooklin, Ron Eddie, Somervile will probably be better than most 1/18th scale now on the market.
I used to deal with Modelauto in Leeds (this was in pre web days). Try them as a first port of call.
PS if you want landrover/range rover models there are heaps of them as well.
Kia ora,
Mark
