Yeah, all the advisors I have spoken to have been polite, but as you say it's as if they just type in the SLI and read what it tells them. However, would've thought that the dealer would do just the exact same thing, or even just be doing what I am doing by contacting Cupra Customer Service for an update.
I have actually just spoken to Cupra about my car and it is still showing as in production, so when I asked "is it built and awaiting chips?", I was told "yes". I was advised to try them again next week for an update, with no mention of contacting my dealer, so will get back on to them next week, although may give my dealer an e-mail as well just to see if he has any more information.
