The only 'accent' these guys have is 'NPR-East Coast lib.' You don't listen to their show to learn anything (much) about a car. You DO learn a lot about 'girly-men' and enviro-wackos. Their politics suck but there are others who push the agenda a lot farthter than these two. They are definitely out of the income tax bracket and live at a leval that is out of reach of anyone who doesn't own at least three very profitable auto shops. Their cheap and relatively harmless entertainment for a Saturday morning.
Let's be compassionate conservatives and understand that they have grown up reading the Boston edition of the Hanoi Globe all their lives. Add in the Boston and national TV outlets, they don't have a chance of knowing what's right. The whole area is infected. New York and Long Island are just as bad with the NYT, Newsday and the Daily Snooze, all lefty garbage.
So, get beyond that. Get beyond that it's not really a car repair show. It's comedy and they're funny.
