The head gasket issues all seemed to go away with the engine redesign prior to the 13 model year.That GM is easy to repair, parts are cheap, insurance low cost, and no worries if you get a dent or scratch. Way more roomy and comfortable than the Subaru. Gas mileage is only going to be minimally less than the Subaru. It only weighs 200-300 pounds more. The 4.6 is bulletproof and will easily go over 300,000 miles without a major repair. The Subaru will probably need head gaskets in half those miles. And in a wreck, the bigger car will often come out better.
