It's kinda stupid that everyone was like "show us your timeslip" and when he does practically noone believes him. So you've seen it and it's not good enough - what kinda timeslip did you expect to see?
And, if if his story is so impossible, and he doesn't have the proof you need, then why argue about it.
Who can say whether he is or isn't lying? He's happy with his car, lets just drop it.
