I have a 2013 S85, now getting close to 6 years old. About 50K miles, running like new. Just so you know, the 2013's don't have a lot of features that the newer models have. They may have parking sensors if they are from near the end of the year. (Tesla does continuous improvement, not tied to a model year). We had an aftermarket parking sensor kit installed in ours. Almost no drop in battery capacity in 6 years (maybe 5% or less). We got the rear seats in the trunk for our grandkids and that has worked great. Tesla service has been fabulous, especially compared to my previous ICE cars. I had fancy Lexus models since 1990, and there is no comparison with the Tesla service. I hate going to Lexus for service, they are constantly trying to upsell and fix things that don't need fixing. I don't know the service situation in Hawaii however.
You can PM me for any further questions.
