[...] Is it hard to keep up with changes in cars?

Road and Track comes out with something new every month. Some of it makes it harder for you to work on stuff, because they make it where the mechanic at the dealership can diagnose the problem with a computer.

I guess that makes it harder for you?

Some times it's trial and error to find the problem. And when people come in, they want you to tell them right away what it is that's wrong. A lot of times, you can't tell right off the bat.

What can you tell about the people from their cars?

Sometimes people drive really arrogant sports cars, and you can tell a little about them. If somebody's in a smaller, more modest car, they might be really nice people. Occasionally you see a big dude driving a Geo Storm. You never can tell.
