I am in the market for a 90D or a 100D - still early in the buying process so willing to wait a few months. I drive a lot for my job (25k miles per year) and was going to get the Mercedes E63S next year as a CPO as the warranty comes with unlimited miles. However the more I drive my wife's X, the more I realize I need to get a Tesla of my own. My ideal car would be a used one with under 20k miles AND a warranty that goes to 100k miles. Do the CPO cars warranty go to 100k miles only if they are high mileage cars? What if I bought a low mileage car from a private party - can I add the 100k mile warranty on at that time? I still have plenty of time so I am posting this way early to start getting some ideas. My job is a 250 mile (mostly highway) journey so I am thinking the 100D will be suitable for my needs. There is a Supercharger on my route if needed if anyone is wondering. Hopefully I will be joining the club soon!
