I do not trust dealerships. Their service department is extremely overpriced and I have been screwed by them a few times, Nissan dealership. I would find a local shop that you trust. For me it would be a garage attached to a shell station up the street. Their prices is 1/3 of the dealership and I can give them my own parts that I get off of the internet which is sometimes cheaper. I just got a service that the dealer wanted $1800 for done at my local shop with me supplying the parts for around $550.
The advantage to dealerships is OE parts, factory training and an
escalation process if something goes wrong. Most dealerships are
extremely CSI conscious these days and will do anything to avoid a
bad survey; is costs them bucks from the manufacturer.
Bringing your own parts can bite you in the ass as most mechanics
will not warranty the job they're doing unless they sell you the parts.
If you buy a cheap-shit set of brake pads from Pep-Boys and they
squeak like hell you can't reasonably expect the mechanic who installed
them to take any responsibility for their performance. Screwing the
shop out of a reasonable profit on parts is rarely a good idea.
That being said, do watch out for unwarranted upsells at dealerships.
The service writers are paid on commission and will sometimes try
to sell things that are on a maintenence schedule, like belts and hoses,
that may not be worn out at all.
