I saw a demo in Los Angeles that I kinda wanted. The only major difference is that this has FSD. I chatted with a representative (named Jeremiah) for quite a bit just now. He was so responsive to all my questions. I learned that I wasn't getting much of a discount by going with a demo model. I learned that I could get a $10k discount if I remove the FSD. I can only go see the car if I place the deposit on the demo model. I will get the $100 back since I'm essentially ordering the same car. After placing a deposit, it should take about 1-2 days to take delivery since I'm close by and there will be no transporting of the vehicle.
After all this, I've decided to just wait it out and get my vehicle with the interior I want, with no test drivers having been in it before. The demo does have radar though. But it also has the older battery. If I don't get my VIN in the next 2 weeks, I'll probably be regretting this decision to pass on the demo.
