Unfortunately, they we're willing to let my wife and I walk away unless we gave them the required info to run the credit checks. We were definitely caught off-guard as I did a lot of work before-hand to make sure we wouldn't have to do that.
I'm still not happy about that part of the sale, however it really only represented about 5% of the actual sale, the other 95% was one our best car buying experiences we've ever had. Unfortunately, that 5% will be what I remember...
I probably will be writing Nissan corporate about that, but they probably encourage it for data-mining purposes.
