Is this a scam?

I got a call yesterday from the Pontiac dealership where I had my car fixed a few weeks ago. They said they are looking to buy back cars, no matter what condition, at a profit to me. I've never heard of anything like that. I haven't had a chance to talk to my mom - since she's in the car business - but maybe they're just trying to get people to trade in for new cars. I'm in the market for a new one though, so it might not be bad to go for the meeting anyway.
