I think a dealers a dealer, there going to tell you anything just for you to bring your car by. If you know what the problem is, stick to that don't let them pull you around tellin you everything else you need to buy, but than again if it's warranty work, I think the car rentals are free so either get the rental or tell em to call ya when the part comes in.. Try to find a service writer that knows what there talking about, it makes it 10x easier.. I've heard good and bad about every dealership in the valley..
And as far as an alignment, after taking mine to Vals they said how it was when I brought it in the dealership woulda left it on the lift for 2 hrs and charged me I ever so needed left arm.. there great for warranty deals but anything else,, blahhh
