Whoa, hoss - bad move in my humble opinion. Do you want to just vent and embarrass the dealership and yourself or do you want resolution?
You have owned the car for 6 months. Now you pull a Carfax and want what - a refund, an additional discount, to trade the car for something else, free service if there are suspension related problems, an apology - I am serious- what is it that you want to achieve?
A buyer is obligated to do some due diligence, especially if buying a USED vehicle. You have had use of the car for 6 months. They aren't going to just write you a check for what you paid for the vehicle , ESPECIALLY if you storm in to their sandbox calling them crooks. Do you really think a seller is OBLIGATED to tell you about every accident the vehicle has been in? Where is the line drawn- a bent bumper that was replaced or a car that was a twisted burned shell after a multi-fatality catastrophe? - a little vivid but you get the point. To me, it seems that the line has been drawn, right or wrong, based on whether damage has been severe enough to warrant a salvage title. Some damage can be repaired properly such that you really aren't going to notice any lingering effects. One exception to that, again in my opinion, is the paint. It would be rare for a $75,000 repair shop paint booth to produce the same quality as a manufacturer's $750,000 electostatic paint booth. However, a salvage title is a scarlet letter. You said the vehicle does not have a salvage title so that is not an issue. The other issue is whether you directly asked about prior damage and whether you were dealt with truthfully. While a seller may not be obligated to disclose facts, even relevant ones, every business transaction requires truthfullness by both parties. Otherwise there is no meeting of the minds.
I went to the other thread and read the CarFax on the vehicle. The accident was in 2003 so CarFax most likely had this damage report on it when you bought the vehicle in 2006. However, please read the CarFax report carefully. Damage is listed as severe when the car cannot be driven from the accident site. Something as simple as a broken radiator hose can keep the car from being driven away from the accident site. Frame damage is reported whether it is minor or major and can often be repaired. CarFax often uses accident reports to gather data. This means that they are going off the police officer's assessment of damage. There is a case number on file. You could request the accident report and it may show where the car was taken after the accident. Maybe the dealership could help you track down exactly where it was repaired and what was repaired.
From what I have read so far, the dealership probably knew there was prior damage to the car. However, you should have been proactive also. Proactive means pulling a CarFax BEFORE forking over the dough. It also means that if you asked and they lied, you got it in writing. Otherwise, your satisfaction now depends on the cooperation of the person across the desk from you when you discuss the issue. Remain professional. If the dealer is reputable, he wants satisfied customers. The two of you will figure something out. If not, you lose a few dollars but don't lose your dignity. If he is a scumbag, don't give him the thrill of knowing he put one over on you and won. I have driven 9 hours pick up a vehicle at a dealership to avoid doing business with the same brand dealership 2 miles from my home. This is my way of saying "Fool me once- shame on you, fool me twice- shame on me". If the Used Car Manager isn't responsive - stay cool. There is always the dealership Manager who may or may not be the dealership owner. After each step, let us know how it is going.
