<prompt> Human: Heres the story and what I need help on. We recently got my wifes car paid off. My car was in need of replacement. I had my eye on the Toyota Tacoma for quite some time, so finally, I found one at a local dealer Not a Toyota dealer, but a new car dealer that was exactly what I wanted. They had it listed for 30,998 online. I felt like that was a good deal. This was right at KBB and NADA values 30,500, with obviously a little extra. So I felt confident and went in. When we started to talk, the dealer told me the Internet price was actually the price after paying a 20 down payment. Ok ok, so we started talking, and of course it got into monthly payment talk. Being young and dumb, I didnt think to haggle much and just went with it. So in the end, we ended up paying just over 36k for the truck. It was over KBB and I knew it. So after getting it home, I was rummaging through the glovebox looking for the maintenance schedule and I Found the ORIGINAL bill of sale from the new Toyota Dealer. The previous owner paid 30,500. Fk. Now I feel like a complete idiot. I paid 6000 over book value and over what the truck was NEW. Ever since this realization ive been beating myself up. My wife and I budget extra monthly payments each month. 500 extra on student loans, 100-200 extra on car payments, so our 7 year loan got that because it allowed us wiggle room would be paid off in about 5 years with the extra payments. Thats all fine and dandy, but were still gonna end up paying well over 7000 more than the car is worth. This has been really bothering me, and I havent talked to my wife about it, because Im pretty sure shes gonna get mad. She was there when we signed the paperwork and she knew how much we were paying, but she didnt know the KBB value or how much it was new. So heres my question:A: Has this ever happened to anyone else and howd they manage it?B: Is it possible to go back to the dealer and renegotiate price after purchase? Ive had it less than a week and only put about 300 miles on it. I feel like I got really screwed and would really like to fix the mistake I made, and pay closer to KBBNADA for this truck, instead of lining the dealers pockets, which is what ive done already.EDIT: Wow. I had no idea id get so many responses. Thank you everyone who has responded with their input. Its pretty clear that I definitely did screw this up, however Im only 23 and have a lot of life ahead of me, and part of life involves learning. Ive learned by mistakes in the past, and Im a firm believer that mistakes are what teaches you the most over anything else. My workplace has just started offering a Dave Ramsey course as part of our benefits package. I thought he was kind of a crock at first, but I believe im going to take them up on their offer and see if his teachings can impact me in a positive way.UPDATE 2514 6:15pm: Took many of your guys advice and talked to the dealer. I talked to the original sales manager I talked to initially. I asked him if he could explain why I paid much more than the KBB, NADA, and the Internet price. He chalked it up to Market Adjustment as theyre hard to find. I explained to him thats not the case, and he just said It is what it is he obviously didnt care about my case, as he had a smirk on his face the whole time and chuckled with people walking by. I mentioned that I consulted with Reddit as well as was considering a Lawyer and he just said This is America, you have that right so its obvious he doesnt care. I guess at this point the only thing I can do is try a BBBFTC claim, and just write up a report on yelp about my experience and chalk it up as a learning experience. I did get the whole exchange on voice recording though on my phone. I was hoping to get him admitting it was high, but he didnt, he just chalked it up to the market. Again I thank everyone for their suggestions. Some of you think im a fucking idiot, which is fair, I probably am, however many of you have provided some great suggestions on future car buying and what I need to do different next time.  <response>: You done fucked up.
