I am looking into buying a used Model S in a few months and have started to look at the cars extensively to see features and differences between them as well as what I can and cannot live without. My question to you gurus on here is if my max budget is around 55K what is the best option for me? Do I really need the dual motors, I live in Kansas City and we get snow sometimes... Will I want the bigger battery, or other features right off the bat to make the driving experience better? Should there be anything I should look out for when buying one used? Any help with these would be awesome!
