I've worked for Sears Canada for 8 years now (Information Technology, not the auto center). We have discontinued offering auto service in all our stores north of the border & are "out sourcing". I'm personally not a huge fan of getting my car serviced there even with my 25% discount! lol
I've heard really bad stories regarding ripping off customers from Sears stores in Canada. I would assume things are better in the U.S.
I have a regular mechanic with all the special equipment & a reliable back up should I need one.......very picky about whom I let service or even touch my car.
