I drove a Saab (had a 1965 3/4 ton Ford F250 with a Clark 5-speed transmission too) for many years before I ended up with a 1983 LandCruiser, which I kept till last year. Sold it for more than I paid for it...
I have had a few Volvo's too and only have fond memories of the 164;
If you go for the Volvo, stay away from the older 4 cylinders... underpowered. Also make sure it is electrically sound... that was another weak point with them IMO.
