The last time I checked with my Subaru dealer they wanted around $1200 for the tune-up for 30,000 miles. I'm almost at 40,000 and still haven't had a single tune-up. One of my friends used to be a mechanic and said $1200 was steep, all it needs is some new plugs, wires, etc but not $1200 worth of stuff.
None of my past cars have been that much to get tune-ups, and I admit to even having them done at Pep Boys from time to time. This one's an 08 WRX so I'm staying away from Pep Boys, but would a local shop make a better choice for a tune-up?
P.S. I had my brakes done at a small garage and I had the guy hook it up to the computer a few months back and he said it was fine, didn't need a tune-up. I just hate to have to save up that kind of cash for something I might not need. I'm not exactly well-to-do with money.
