I hate taking cars for a service. Not just because of price, I put Mobil 1 fully synthetic oil and NGK spark plugs i my cars, and when I tell them the oil and spark plugs are fairly new and OK, they still change them, even when they say they wont!!.
So I get some cheap oil and very cheap champion spark plugs at a hefty Nissan price. The car leaves the garage in a worse state than it arrived.
