Not so much as a bitch, as a warning:

If you buy a car from a dealership and the salesperson/staff tell you you will get a "Customer Satisfaction Survey" in the mail in 4-6 weeks, DO NOT RETURN THE SURVEY TO THE DEALERSHIP! These surveys MUST be returned in the mail (often going to head offices) for an unbiased assessment.

They may offer you a free tank of gas or a free oil change... keep in mind this is a ploy for them to sneak a peak at the survey, which is supposed to never end up in their hands.

Not all dealerships are nice... some have skeletons in their trunks. —Crooked Car Salesperson Tricks
