I got one similar when I had my 1500 Chevy at A&M. I went and did it. Easy money, and it's just basic focus group stuff, like the 'Mahk' Chevy commercials. What do you like, not like, would you change, etc. That was 2001, so I'm sure things are different now, but it was no big deal. And if it's legit like the one I went to, they do not try to sell you anything. Seemed like a completely non-partisan research deal just trying to gather info.
