If car dealerships are of the impression they're better than you, and you like that, come here! Getting my due bill and service was an awful experience afterwards as well -- they make you feel like you're inconviencing them. I bought my car there nevertheless because it was the only used CLS within 50 miles with the low mileage I wanted. Buy what you need and get out, I'd recommend Phoenix Motors -- they're much more friendly. It felt like a Scottsdale dealership, not what I expected of Chandler.
