Take a look at things like the grips, footpegs and so on - does it look like a lot of wear there, commensurate with the claimed mileage?
On Norris' point, I have to admit to thinking the same upon seeing this thread's title. Just for a fleeting moment, of course.
Wouldn't have crossed my mind to mention that I like to ride mine away brand new - maybe touched by a few people in the showroom, but not actually ridden. And tbh, I'd shy away from one abandoned on the side of the road with 1/4 million miles on the clock.
