...also to be honest I have never seen a S40 on the road and I’m in SoCal where Tesla’s are as common as Honda’s
Only one brown P85+ with AP1 is known to exist.In green or brown.
My recollection is that back in 2012, Model S cars were initially not delivered with badges. They added the badges early in 2013 and you could have one installed if your car didn't get one. Then the 40 was discontinued in April 2013, so the window for getting a 40 badge was pretty short. I could not find an image of a 40 badge, but according to this post, they may have existed at some point in March 2013.Might be difficult to spot those, because I don't think there were any 40 badges made (at least I've never seen one). OK, my son is sitting next to me as I'm writing this and we have a difference of opinion...he thinks we might have seen a badged S40 somewhere, but I don't remember this. Could be I'm getting senile. .
Every Tesla in the for sale if you believe the sellors...
That doesn't have Autopilot. The "unicorns" we're talking about are the few that were built with AP1 after 9/17/2014, at the tail end of the RWD P85/P85+ models' existence. You couldn't order a new P85 or P85+ after 11/5/2014 when they were discontinued in favor of the dual-motor P85D. The green and brown paint options were dropped at the same time.
