Don’t do it. While we all love them, they have far more problems than a modern Tesla, are more expensive to repair with limited repair options (he might wait months for some repairs), and certain things cannot be repaired, such as many battery failures.
He would be much happier if he bought a Model 3.
WRT your questions:
1. I do not know off the top of my head.
2. Very. Don’t think I ever got out of Medlock’s with less than a $1k bill. Similar pricing (or higher) at Tesla.
3. Tesla will still service them, but he may wait a while. He may also look at The Electrified Garage, which I think now has a Florida location.
4. No. But there are still some new warehoused parts that Tesla has and there is a robust salvage market for parts. Some folks are having parts made themselves and sometimes do bulk buys on this forum.
5. Mediocre. It’s Tesla’s Achilles Heel. I’ve owned several Teslas and have had good and mediocre experiences with Tesla. Wait times for appointments and parts are the biggest problems. And they are BIG problems.
6. Power Electronics Module (PEM) failures. Battery failures.
7. Just don’t do it. He’s not a car guy, has never owned an EV, and doesn’t take care of his cars. Not the car for him.
