If you want to buy a 9-5 with a diesel engine you should wait a while. The 2.2 is old, and should be retired. It has been replaced in the 9-3, but for some reason the new engine isn't available in the 9-5. The new engine is more economical and runs cleaner. It's a 1.9 that has 150 hp, and 150 hp is a lot of grunt when it comes from a diesel engine!
