Thanks @jrbe. Sorry for not responding @P.S.Mangelsdorf, I am not sure why but I am not getting notifications on regular responses (but am when tagged it seems).
I am thin on details, but happy to provide any info I can. These cars were part of an autonomous driving program (robotaxis) that ended, although I do not know why, but these cars were barely used - they looked like new inside and out. I was told (so this is just rumor) that someone died and they shutdown the program and sent these cars to a junk yard to be crushed. I personally pulled these so I know care was taken and I made sure i got all the connectors and didn't ruin things needed (like brake lines cut on the car side of the connectors, etc).
The cars were built in ~2020 so possibly pre-production or based on early release candidates based on notes taped to things, and likely have heavier duty springs to account for additional weight in the trunk (hardware to support the autonomous driving). Someone had clearly spent a lot of time and money prepping these cars - all the additional wiring for lidar and screens was carefully integrated into the wiring harness, and exterior modifications were made to the cars to support the lidar and all the related autonomous driving stuff.
Anyway, i don't want to post too many pictures publicly of the cars since it's all here say and someone seemed to want to keep this on the down low, but I added a few.
PM me if you want to discuss more. I might be headed that way in late January, and could try convince my wife to bring one down if you are interested.
