Just did mine today at Dick Ide VW in Rochester - allegedly the first one in town! It was their first time too, so they didn't really know what to expect either. There was an "ambassador" (dude with the tablet who did all the talking), and a "local representative" who I guess would be handling the back end such as storing and shipping out the cars. They didn't know how the EFT worked, and asked if I had already entered a bank account # on the site (TBH, I couldn't remember since it was over 2 months ago), but luckily I was able to get on here via my 'phone and read this thread, which put my mind at ease (just waiting for the EFT email now).
Whole thing took about 15 minutes, and the email receipt following closure was instantaneous. I didn't get a paper receipt, and they kept my registration document (I'd already made a copy at home). The only delay was in removing my plates, because the screws were rusted and stripped, so had to be drilled.
PRO-TIP: put some WD40 on your license plate screws the night before your turn-in, to loosen them up a bit!
