Sterling McCall Nissan shopping spree promotion - how free is this money?

I got a letter in the mail from Sterling McCall Nissan today, offering me a $1,000 shopping spree just for test driving a car before December 31. I'm guessing they'd like to make their numbers this year, and that Nissan is underwriting most of the cost.

If I go, I'll post and let you know how it goes. I sure could go for jumping through some marketing hoops to not ever buy from a dealership, ever.

Number of new vehicles I've ever bought: 0.
