Hi: We have a 1997 Legacy Outback. It has been parked for the past few months due to problems with it overheating. ( I start it & let it idle for 10 minutes every few weeks.) It needs to have the knock sensor, water pump, timing belt replaced. Estimate from Suby dealer is </body>,063 I want to use this as a trade-in for a Saturn Vue. Which would bring me the best return - trade it in 'As is' or fix it first? And no, I don't want to go the Private Party route, too much hassle. Thanks, Phil
