should've gotten the 5.3L V8 in our Saab 97X :(

shuts down to 4cyl and there is a SC for it

but, this past summer when I got it when gas was $4, no dealers had a V8 one that was CPO 6/100k -- at least not any without driving 300-500+ miles. it wasn't a deal breaker since the V8 only tows 900 more lbs and gets slightly worse average daily mpg if you don't do all highway.

just curious :D

Much harder to do.
