Well my 2 cents are always free so ...........
I've traded with people on here that have been members for 4 years, 4 months and 4 days, really doen't make much difference. The thing that does make a difference is communication. The "senior forum" might not be bad but I think the "feedback forum" would turn into a pissing contest and a "my dick is bigger than your dick" forum after the second post !! Please, " he said it had 2 tears in the front seat and it has 3, WTF !! Lying Asshole !! " get my point ??? Communication is the key for any deal, talk to the other person, swap photos (up to date would be nice), set up everything before you hit the highway. Remember shit happens, "Oh, i forgot about that dent", "those tires aren't that bald to me" ect, ect .... its all part of the game. Hell, I'll admit, I don't always send back responses, get in the middle of a deal and then forget to call or text back, but I always try and represent the car/truc/whatever the best I can.
IF ONLY SARCASM WAS A VIABLE COMODITY
Mautofied=No car payments ! 
Trade and work it man!
Just like I've said before, There should be a rating system to where you can put or mark on a 1-10 scale on satisfaction, no shows and such. That way we can look at their profile and know who where dealing with. Its especially hard to deal on here because theres usually no one to trust. Not everyone reads these com. forums. But if we had a ranking system or something near where it tells you where they live and such, then we could just view it , then take it unto our own hands. Thats why if you look at my profile, my history is very very low. I dont trust anyone who makes me an offer or accepts mine. Its a little scary doing business on here just because I cant afford to make such a loss. But this site is the only one that I can get attention to my ride just because no one is interested here where I live. But its very stupid that we have to go thru this......Something def. needs to be done.
