I am looking for a new daily driver for my gf... i found a 98 legacy outback it has 200,000 miles with a blown head gasket. I did a little research and it seemed like this was a common problem with the outbacks. I was going to buy it for $600.00 and fix it myself including having the head machiened. Is it worth the work or am i just buying something that is going to bite me in the ass down the road?
