So how hard, really, is the maintenance on these Subaru's? The prices at my local dealer are a little high for my liking. $230 to replace the oil in front and rear diffs? $300 for a trans flush?$200 to flush braking system? $80 for an oil change? Seriously wow! I can do all of this in my driveway at home. Just wondering if there is something special about these cars or if special tools are required that the dealers are so expensive?
