Regarding VVC acquisition for anyone in the Portland, OR area, I tried to enlist Mercedes of Wilsonville's help. I would say they were worthless, but they were worse than that as they assured me over the phone that they could help, before I made the 40 minute drive in. Sat around with the "product concierge" while he tried to figure out what a VVC was (despite me telling him in detail), then I finally convinced him to talk to the Sales Manager (he was literally afraid to bring it to him), and he was clueless and disinterested.
I called MBUSA's 800 number, and they reached out to Wilsonville to prod them on my behalf, assuring me I would get a call. No call, of course.
I called MBUSA again, and this time they called Mercedes of Portland, who were excellent. They emailed my VVC within about 5 minutes.
So, FWIW, Portland MB seems to actually KNOW about their products and CARE about their rep. and customers.
