I have absolutely no patience with car dealerships and their tactics, few relatively recent experiences below:

Went to Toyota dealership wanting to test drive Camry -- the sales person wants to go through his BS worksheet trying to match my needs to the appropriate car. My answer to "Why I am interested in Toyota?" question was: "Whenever I buy a new car my wife always takes it and I don't get to drive it. She will absolutely not drive or be seen in Toyota, so it would work for me." Refuse to answer any questions about whether looking to finance/ lease/ pay cash etc. Finally have test drive -- car was fine enough and I tell the sales I guy it's ok enough and I would be willing to buy it at the advertised special price (have the ad with me). He said there's no way to get it at that price, I say there's no reason to talk about anything else then and raise the speed up to 80 MPH on highway on my way back to the dealership. Guy tries to talk other good deals, I remain quiet and just leave with my friend once at the dealership with promise to contact State AG's office for false advertising (not that I actually bothered).

Local VW dealership advertises special price on Passat - the price is close to $5000 less than anyone else can do. We meet all the criteria (loyalty, grad, etc. discounts) and call ahead to verify that the ad car(s) is/ are on the parking lot. My wife and I get to the dealership and they tell that the ad car is still in the shipyard, but we could test drive one almost like it. We refuse and walk out, manager runs after us and magically announces that someone just brought the car to the dealership. We do test drive, my wife likes the car... I tell the sales people that we will pay the ad price, not penny more. They start doing the paperwork and about 10 different time I catch them cheating/ changing the numbers. Final straw was some BS $300 fee they came-up at the last step -- I took and ripped all the completed paperwork into thousand pieces and then threw it towards the waste basket.

Dealership called my wife back the following day and asked whether we wanted to make the deal. I told that if they changed a penny we'd walk again -- that evening we got out car in about 30 minutes after arriving.
