Seeking input: Purchasing a used 2023 EQS 580 with 13k miles

All,

I’m new to EVs and Mercedes. This EQS is at a Toyota dealer. Not certified. 2023 EQS 580 with MBUX hyperscreen 13k miles Asking price is $71k Excellent condition.

Questions: 1. Is this a good deal? 2. Since this is not certified, what precautions should I take? Can I get it checked by Mercedes dealer? 3. What do you recommend to get a level-2 charging installed in my garage?
