The difference between a “pleasure driving” and a true marathon cart can be thousands of dollars.
Good used, meadowbrookes, easy entries (perfectly fine for pleasure shows and driving) come up well under a $1000. all the time. This is always going to be your cheapest bet. Except the little metal rigs with blow up tires (which I don’t like).
A fancier rig is going to be more.
A used good marathon type for a smaller horse…will cost you $4000. In this case, because they haven’t been around THAT long, and they hold and hold their value, buying new is definitely an option. Basically, a marathon vehicle is an expensive option (new or used). Buying used isn’t going to save you much money.
Carts aren’t like saddles, they aren’t a dime a dozen!
Places to look:
AUCTIONS!!! Martins, those in the mid-west, the Perry auction in the South, the Dixie auction in NC Auctions can be your best bet if you really spec out the vehicles before hand. Know that the popular models that everyone knows about are going to fetch the best prices, so you have to look for the undiscovered gem. For instance, pioneer forecarts always fetch more money than you can buy them new in Ohio! But easyentry carts that have cosmetic issues, are dirty, etc. can go very cheap.
Craigs list: just keep watching those ads and those in surrounding areas.
drafthorsestuff.com Often has pony sized stuff.
The carriage driving classified tends to be expensive. I don’t know why but people seem to ask more for used stuff than it costs new! It is truly weird.

Ebay: Occassionaly has stuff but again, it often seems to be dealers selling used stuff for too much money or it is new and VERY cheap in quality. But then a gem will pop up. Look for keywords that most people don’t search for (buggy, horsedrawn, roadster, etc). Sometimes you can pick things up because the seller just didn’t know how to describe the items.
Lancaster Trader in PA often has ads, if you live in PA.
