I take my car to a dealership too. I don't have a great deal of choice, but that's another story.
My list, the first year, included : New air-cabin-filter, oil filter, oil.. some other sundries. They even helpfully brought the air-cabin-filter with them to the waiting area to show me exactly how dirty it was! Full of gunk and y'know... crumbly leafy bits. $60 to replace that.
Since I have no knowledge of cars, I went home and decided to 'get me some lerning..'
Air filter = $3 online.
Changing air cabin filter is literally.. (and I *actually mean literally*) case of opening the glove compartment, depressing two clips and pulling it out.
Next time I went, they brought me my air filter to inspect once again - asked me if I'd like it changed - since it was 'so awful'.
Me: No, thanks - but since you have it out already, and you have to put something back, would you mind putting *THIS* one back in, rather than the one in your hand?
Engineer: Sorry, we can't do that..
Me: No worries, I'll just save the $57 and pop it out once you're done.
etc etc. There's like a dozen little things like this which are *completely stupid* that they try to bag you for.
I hate my dealership. They spam me every six months telling me my car needs a service because.. y'know.. ITS BEEN SIX MONTHS!
Despite me swearing at the fuckers that : I don't even drive the thing anymore, take me off your goddamn list, I'll come in when I'm ready.
Their showroom could go up in smoke and I'd actually be happy.
