I would not worry about the extra mileage but I would definitely ensure the car is sold to you with an extended warranty, partly due to the lower than average reliability predicted by the Consumer Reports survey. Even without the Consumer Reports report, I'd be weary of owning one out of warranty since only Tesla can fix any issues that come up.
I should probably go look this up myself, but as I recall, these warranty issues, although "higher than average" are all small things. Even the drive train replacements were done for fairly minor issues because it is easier to replace the drive train than tear it apart to replace a shim. Most fixes are like when the door handles don't work as expected: Replace. Done. But it's recorded as a warranty issue. My hood latch bent. It was replaced. I can't think of anything that was major, and the car is still the best thing out there. Pano roofs had squeaks. They were fixed. Shoot, with a gas car, you couldn't even hear the squeaks.
When Tesla gives a warranty of "eight years, unlimited (or infinite) miles", mileage becomes meaningless: What percentage is 80,000 miles out of infinity?
But warranty? It all happens right at first. Especially with early production, there were known problems. Windshields cracked, and were replaced. Inverters failed. And were replaced. All for free.
I don't see the concern and worry over maintenance issues. I would far far rather have this fantastic new technology, and maybe stop by the service department once every hundred thousand miles, than have a hundred year old technology that needs maintenance every few thousand miles, plus needing to add polluting, planet destroying fuels and lubricants every week.
No comparison.
