I went to Santa Monica a couple times when I first bought my Q. They were pleasant and professional, as I'm sure most dealerships are, but way too expensive for me. I went in for the 60k service. Ended up paying about $500, mostly to have the oil and plugs changed, and to perform some "inspections". I didn't get the feeling the techs were *REALLY* competent, though better than the average grease monkey. The parts department personnel could stand to take some classes in customer service, I think. I doubt dealerships are performance oriented at all. You'll need to go to a specialty shop for that. Unfortunately there aren't a lot of mods made specifically for Qs. Just plain economics at work. If you need stock parts you can save a lot of money by going to Scottsdale (
