In the process of dealing with Arlington Nissan in Arlington Heights, IL. Been talking to Alex Chernis (the GT-R/Z expert there) as well as Bob Jacobs (the internet sales manager).
Alex is by far the most knowledgeable salesperson I have EVER dealt with. When I went there for a test drive I probably spent an hour and a half just shooting the breeze with him. I guess he is one of the few sales guys in the area that has been through the program for selling GT-R's as well. You can tell he is a cool guy because he dresses more like a shop mechanic than a sales guy
Pending any hiccups during the actual sale I highly recommend these guys.
