that's because 80% of the time dealers lie. especially about the brakes.
maybe they see that he is older and might not know about cars, so they think that he's an easy target.
it's funny to see how my mom (who drives a VW) and my g/f (honda) get treated when they come to a dealer.
i kinda stand back and pretend like i'm not with them.......then when the tech starts bullshitting to a point where i cant take it anymore, i get in the middle of it.
one time i got furious when a tech told my mom that motor oil and tranny fluid have to be changed every 3k miles.
