I bought my 370Z at a Toyota dealership and they didn't know anything about it.
Test drove a GT-R at a Toyota dealership as well and they didn't know anything about it
On a plus note my salesguy at the Porsche dealership that I bought my IS-F and 911 from knows his stuff. He said all the sales people are sent to Porsche driving school regularly and get to test drive various models.
When I was test driving my 911 he was giving me a bunch of driving tips and showing me what all the buttons and stuff do. Now that was a great salesman! No BS, no hassle, knows his stuff
