Thanks for all the advice folks. We can't justify the cost of a 2015 right now, so 2013 seems to be the sweet spot for us. I have been through more of the potential issues that we might face assuming we have a warranty on the motor and battery but nothing else; and once that warranty runs out.
I think the big deal breaker for repair for me would be the battery. I could imagine fixing almost everything else based off what I know about the cars. The door handles, charging module, MCU, brakes even the motor bearings would be a pain but I think I could do it (or worst case pull the motor and get an Ebay replacement).
The battery is so big it would be hard for me to drop it and then have the time and space to peel it open to swap a battery module out, assuming I got an Ebay replacement module.
So at the moment I'm focusing my searching on any cars that have a replacement battery pack that is newer than the car, or a car with extended warranty on the battery (although I think this rules out non-Tesla dealer cars).
I did find one at a vegas dealer that seems to have a replacement 90kwh battery. As far as I know 90kwh wasn't available in 2013 so seems to be a replacement. Trying to get a pic of the battery pack sticker to confirm. The guy also claimed warranty until 2024 but I take that with a large pinch of salt unless I could verify that properly.
