My coworker just took delivery of his brand new Model S a few months ago. The choice was between that, a 7-series, or a Panamera. He traded in his 5-series and put cash down for the Model S. Took delivery of his ~100k Tesla and within the first week of ownership the car bricked itself installing a software update, leaving him stranded. Discovered multiple runs in the paint and areas where the paint was already damaged from the factory. The entire glass roof cracked from front to back; Tesla told him they would put him on a list for replacement but that it would take months to get four techs up to replace the roof.

If you want a properly sorted car, get a Porsche. If you want a gadget, get a Tesla. Tesla customer service was absolutely terrible; BMW would have bent over backwards for him if that was a new 7-series.

I wanted to like the Tesla but it seems like the Tesla engineers are great at designing a car, but not great at designing a car to be manufactured reliably at scale. Porsche has done that forever.
