Hey Folks - please pardon me, I'm new here and new to ATS-V (coupe). I got what was a "Manufacturer Vehicle" with serial number 100007, manufactured February, 2015, which is actually before the press release inviting orders for the car. Anybody have any info on serial number sequence. Also, is there any way to completely shut off air-flow through the HVAC system? I hit "OFF" and, while it may shut off the A/C or Heat, I note air still vents (flows) through the system. Is there any way to shut it off completely? Thank you, Carl Spagnuolo
