A Tesla without a warranty could be a financial disaster waiting to happen. It may not happen today, or tomorrow, but it will eventually and you will be sorry. $1,000 or more for each door handle, $3,000 or more for a center screen (many from 2012 and 2013 are now delaminating), $1,500 for each charger, DC-to-DC inverters, on-board supercharging, and who knows what else. There is much unproven tech in this car.
I just broke 50,000 miles and I do have the extended warranty. However, as I approach 100,000 miles I will probably be selling my car. I cannot, in good faith, recommend owning this car outside of a warranty period given all of the issues owners experience on a regular basis and the fact that Tesla is still learning how to build a car.
I am now on my fourth drive unit replacement. If this happens after the five year drivetrain warranty runs out, count on $10,000+ or live with it. God forbid a battery module fail after five years, then you're SOL. The last time anyone mentioned it, the 85 kWh pack cost over $40,000. Your vehicle insurance won't cover a component failure. At that point, you might as well junk the car and buy yourself a BMW or Mercedes.
