I know it's been mentioned on other threads, but Texas delivery and registration has been streamlined to the point where the word "process" really no longer applies. They now can handle all the logistics on their end, as well as collect the tax and registration fees. I paid cash, but I could have financed the TTL, as well. You just have to sign a couple other forms (for registration), but that's it. They installed the paper plates before I left--no need for the temporary sticker.
This appears to be a VERY recent development, as my DS (Dayan) mentioned that my March 11 delivery was one of the first he could handle that way (if not the first--I don't recall). I was all geared up for a visit to the courthouse, but it's just not necessary any longer. Can I get a "Hallelujah"?
Regarding the payment, Dayan mentioned that I just had to put in the funds transfer prior to driving away. That took all of about five minutes to do.
With the new developments, this was absolutely the smoothest delivery I've ever taken on a car. No F&I Guy, or anything like that. It was just a matter of initialing and signing a few things, doing the walkthrough, getting the phone charger and paper plates installed, and drive away. Beautiful.
