Have a look and make up your own mind - go there believing the mileage is probably not right, then look for evidence to prove it is right

Maybe he is an honest guy then you have found a good car that is getting difficult to find in unmolested condition. The engine bay looks clean, not over polished and with nicely worn stickers (no new buddies stuck in there to fool a buyer into thinking wow!)
As he is a trader he should be able to organise a compression test for you before you buy and put it up on a lift for you to carefully
inspect underneath - if he says he can't arange that, be doubtful....a trader will organise anything to help shift some steel
