Mine has taken longer than most but it was 36 days from confirmed to in production. You can probably get a pretty good idea as to how long it might take by looking at the Google sheets and find someone that was in a similar position last quarter. Apparently the 60's get built before the 70's, 70's before the 75's etc. The car I listed below looks like it would be somewhat reflective of what you might expect?
