The 2.2 Diesel is supposedly the one to have. The 1.9 is apparently pretty crap and breaks a lot. I think it came from a fiat or something prarrie canoe like that.
Funnily enough I wasn't even looking for one of these and had never considered getting a Saab in my search for a barge (FWD, I wanted RWD). But after reading up on Omegas and finding out unless you get one with a known cambelt change every 40k it'd need to be done because the guides are made of cheese and fall apart taking the belt with it, and even though the engine is the right way I didn't fancy doing that on a V6 engine and I won't pay a garage because I'm skint. I did also consider older Volvos but sadly they've all been bought by twats and 'modyfied dorifto yo yo' (even the auto ones) so nice ones demand a higher premium. Or they are rusty and smell of bodily fluids.
So I ended up with this and it's probably faster than all of the above anyway.
Yeah that's the one. Apparently it isn't that great from reading various sources on the web (including PH!). Strange. Again I suppose that is comparing it to the other Diesel engine and the petrol Ecotech engine in these, both of which are allegedly bombproof.
