> Using a car salesman as your source of info is honestly pretty dubious for any car

You could pretty much replace both instances of "car" with anything and this would be equally true.

Conversation I had years ago:

$boss: Please do $job using the new $overpricedpieceofcrap.

me: Sorry, $overpricedpieceofcrap can't do $job.

$boss: But $guy1 and $guy2 said it would do $job.

me: $boss, those guys are salesmen.

And suddenly $boss was enlightened.
