I wish I could take it into a service center but I have limited options for purchasing a used Model S in the St. Louis. I'm buying a previous Enterprise rental 2018 Model S with 10,000 miles from a dealership in CA. I spoke with Tesla sales a few months ago, they warned me about vehicles being blacklisted, which prompted my post.
Another forum member offered to inspect the car tonight in Pomona CA. I've seen several of these previous rentals on the market recently and read forum members testimonies about purchasing them. I'm hopeful this is a good decision since my options are limited due to budget distance from available Tesla's. I planned to purchase directly from Tesla but wanted MCU2 due to fear of MCU1 failure, which lead me to these reasonably priced 2018 rentals.
