I had my 9 year old car into the dealership to address a manufactuers recall. That is a bit of an inconvenience to get the car into the dealer 10 miles away, but it is done at no cost to me.
Here's where it gets a little interesting.
The dealer calls me during the day, and say they found a few issues:
Leaking axle shaft seal -- $495 to fix
Dirty air filter -- $55 to install
Dirty cabin air filter -- $55 to install
I knew it was about time for the filters to be changed, so I wasn't surprised at that. But I hadn't seen any fluid drips on the driveway, so I wasn't too sure about the axle leak. Google informed me it was a fairly common issue with my model, though.
I politely decline the offer of their services, and 1) order the air filters from Amazon and 2) call my experienced neighborhood mechanic and arrange to bring the car in.
The outcome:
1) Air filters cost $25 total and took at most 5 minutes to replace, requiring no tools.
2) My exceedingly honest mechanic saw no sign of an axle leak once the car was on the lift. He thought that there might be a slight oil leak from the oil pan, and tightened the bolts there. He REFUSED to take any payment for his services. We'll keep an eye on the axle seal.
Net result - $580 more in the stash, and it all took less time that a one way trip to the dealership. Did I mention that my mechanic is a 5 minute walk from home? That's about as convenient as it gets.
I can't claim much in the way of badassity - I just know that independent mechanics are much cheaper than the car dealership service. If the seal had needed to be replaced, the quote from my mechanic was $240 - less than half the dealer's price
