Hey all....I have an opportunity to get for my daughter a 2009 Forester w/ only 80k miles for $2k, which needs at the very least the head gasket replaced. It is going to the garage next week for an estimate. What other problematic things should I have the mechanic be on the lookout for? My wife drives a 2015 Forester, but I understand that is a different animal entirely, so any advice and input would be welcome.
