Sorry I'm late to my own party, but I disagree whole heartedly with the notion that a thread of that kind would be more detrimental than good.
Yes, there were will be *** clowns that do nothing but brag about their price, but in the end, that price might be so good, it leads others to try harder to obtain a better deal......and to be honest, I used one of these mega threads about price/discount when I bought my 2015 to score a very good deal. Without it, i would have never known how good of a deal i could have gotten. Was it the best deal.....no, but it was up there.
I do also agree that some buyers are confused by the buying process and often times cant distinguish what they really paid for their truck due to trade ins, negative equity, add ons and so on, but again, many of the posters would help people understand the process better.
I found those who did understand how to lay out a clean and simple post about MSRP, Discount off MSRP, Rebates, and Final price paid ( with or without a trade ) helped make the post very informative.
