If it was built prior to full production why was it so bare bones? Any ideas?
Most early production cars are low option, volume cars. Gotta get the line running first before they added the option complexity into the process. The exceptions are the early cars that were done for testing, shows, etc. They often have options on them.
What's the VIN? That's the first 12D car I've seen. Note it has that same 9 on the bottom of the tag.
