This process generally works very well with me, with little, if any getting in the car and going to scream at anyone.

1) Go to
www.bbb.org and look up the report on this dealer… keep a printout, depending on what it says, this may be real easy, or take a few (back and forths) in negotiations
2) Fill out a complaint at the BBB website against this dealer and include some of the details in the forum (3 paragraphs should be enough) Note: make sure you have at least 2 names and 2 dates to show you have made the effort to resolve yourself. There are fields for this information.
3) Hit submit, and print out a copy (perhaps save it in Word or something like that so you have an electronic copy)
4) Fax a copy to the dealer, with the fax cover, attention to the owner of the dealer. Say in the body respectfully, if he would like to resolve prior to being contacted by the BBB, or would he prefer to wait.
I did this most recently with Delta Airlines about a week ago. I got my $50 unrefundable surcharge back as well as a complimentary 5000 miles for my trouble. All this even before the got their copy from the BBB, was done by email, and did not have to talk to anyone.

(BTW- I did this at the gate while waiting for my airplane... thank heavan for broadband wireless)
When I get my copy from the BB asking if the matter has been resolved, I reply yes and thank them for their help.
The moral of the story… All businesses take things far more serious if 3rd parties are involved (attorney general, BBB, corporate, a letter from a prepaid legal attorney etc) the BBB is one of the easier ones to engage,…as its all done online.
Now, if they have a terrible BBB file already, it may take a few back and forth’s. With COMCAST, I sent a copy of my local COMCAST report to the county board who manages their franchise and asked them why the county was tolerant of such a record when the neighboring counties (which they all consider inferior)all had reports of acceptable performance by COMCAST. Needless to say I got some free months out of the deal and even had a call from the COMCAST VP

who managed the local COMCAST franchise. So, the takeaway here, is if the buisness does not care about their BBB record themselves, there is probibly someone who they do buisness with that does.....find them
COMCAST still sucks,

but now I at least know people in the Comcast front office to get problems resolved more quickly
Hope this helps
Note: The Better Business Bureau does not have authority to make a company do anything (unless they are BBB members) however most like to get BBB complaints resolved and behind them. Bad reports are bad PR for companies
