Ox carts are nice rides ,you get a better breeze while cruising along and upper ride height visability are excellent.I would think cost in this way ,$7000. initial cost plus $7000 .in 5 years for service and parts ,not to mention down time before you sell it again for $3000. with 215k on the engine .If its not going to be a daily driver I would say go for it but have it completely checked out before purchase .
