Here is a link, from this Board's front page of general info, listing a near encyclopedic schedule of TTD for new vehicle delivery. Maybe a bit over the top, but some good info, imo.

As noted above, my advice is to take delivery on a good weather day, in daytime, and avoid the 'honey, drop me off at the dlr so I can grab the new car' situ, we have all gone through over the years. That, and try to remain objective and questioning & listening vs being emoted because of that New Car Jones.
