Does eBay have a service to facilitate Craigslist purchases?

I responded to a Seattle Craigslist ad for a John Deere tractor at an amazing price. The seller tells me the tractor is in Nebraska and can be shipped to me in 2 or 3 days with eBay acting as a middleman. I am supposed to provide the seller my contact info which she will forward to eBay and then eBay will arrange for the payment and delivery and give me 5 days to inspect the item and accept/reject it. Supposedly the eBay involvement protects both the buyer and seller. Does eBay actually do this sort of thing? Especially for an item advertised elsewhere? I smell a scam but figured I'd ask.
