Got the car. Picked up with 11 miles, so we took a long, backroads easy drive home. Drives great. Really quiet, with light clutch and gas pedals. No weird warming of center console, no paint blemishes, etc.
The only drama was that the dumbass dealer noticed on Mon or Tues that they only had one key. For reasons beyond comprehension, they still had not received it. They clearly shipped it snail mail. We had to make a stink and get them to agree to ship us the key home and reimburse us for the coding that we will do at the local dealer ($130). They had the car a whole week, and could not next-day ship the key and program it.
Anyhow, it's home and we are happy. Miata + M3 is a tight fit in the back garage considering I have a bunch of stuff on the sides.
