I have a plain-Jane 2003 Pontiac Grand Prix SE (3.1L engine) and I am looking for recommendation for a shop in the Twin Cities for head gasket replacement.

The mechanic I normally go to is a one-man shop and doesn't do LIM/head gasket work.

I've owned the car for 19 years. It has 95,000 miles and I've always kept up with maintenance and repairs but it does have some rocker rust I'd like to keep it a few more years but, depending on the estimate to do a gasket job, I may just sell it "as is."

Thank you for your help.

PS: Please let me know if I should post this in a different category.
