Help me out here guys, I just learned my 98 Deville has a blown head gasket and the repair shop, not a Caddy dealer, quoted ~$3500 to repair, which includes doing a valve job. This car has the 4.6L Northstar engine with 127,000 miles, here's the question, would you repair it or trade it in? The car still runs well and I could probably drive it down to CarMax and trade her off. The body and interior is in reasonably good condition, not perfect, but decent. Opinions and comments please!!

Thanks
