The asking price seems just a tad on the high side for me, but then I'm used to reckoning in "Used Bullet Dollars". The mileage is promisingly low, though that is hardly a rare characteristic for Enfield singles, which are often owned as one's second or even third or more occasional pretty "Sunny Sunday" bike, and not one's main mount.
I'd counsel that if it hasn't been mouldering in a backyard uncovered since the Obama Administration as a condo for mice and wasps, and you appreciate the Conti, then it's at least worth going to take a good look at it and have a test ride.
Others have already mentioned the tires. With 1,400 miles on the clock there's a good chance they're still the OEM ones, unless they were swapped out for something "nicer and grippier" (Conti owners generally being a more performance-oriented peg-scraping breed than we happily-plodding Bulleteers). In any event, if the DOT "date code" reveals them to be more than 5 years old, even with plenty of tread left that may be a valid haggling point. One is generally advised that it's a good idea to change tires after 5 years. Me? I'd haggle hard and then still run 'em down to the cords. More info on date codes can be found here:
https://m.tirerack.com/tires/tiretech/techpage.jsp?techid=11The Contis, once Enfield's sole gesture to any sort of performance, have sort of fallen under the shadow of the newfangled 650s. So that might we be another haggling point, seeing as how a brand new 2021 Interceptor can be had (less those "dealer non-preparation" and "title undercoating" fees, of course) for just about a thousand more.
And let's see some pictures of what that $4,700 asking price gets you.
