You are going to have to show me some evidence of cars sitting for long periods and not selling, and everything I've heard is that they are selling, and new ones are coming in just as fast. Its a problem the other OEM's wish they had.
Take a drive today from Hermosa Beach along Vista Del Mar north to Culver Blvd just past the Marine Freeway (90). You'll see all the M3s in the
lot next to (east of) the building with satellites on the roof, at most for you a 15 minute drive. Those M3s have been there for over a month.
Then if you have some spare time, just go back a few blocks to Alda Rd where the Tesla distribution center is and consider helping Tesla by
buying a M3, which you could easily take delivery of today and help the Tesla Balance Sheet (+ cash - inventory). In Q3 & Q4 of 2018, Tesla
never had more than a few M3s anywhere around that distribution center that weren't being delivered. Even the MNL moderator agrees
to there being excess inventory, see up-thread.
