Selling a cart takes just the right timing
it may not sell the first time you list it, but it seems that if its in decent shape, then eventually everything will sell
So, where to sell the cart
Are you near Houston or Dallas
There are carriage driving clubs near both those areas
Im sure there are others in TX, but those are the ones I know
You can go to the American Driving Society website and check the regions for local club listings for the contacts
Most clubs have some kind of newsletter with classifieds

Additionally you can try craigslist
Im not personnallly a big fan of that but some have found it works and is area specific
Also the Carriage Driving List (CD-L)
does free classifieds. Its nationwide, and you have to sign on to it
Be sure to state the location of the cart
