I am currently in the market for a used 2015-2016 Tesla S, but having a hard time on deciding which version I should go for. For my price point, I can get the newer looking 90D which has better range or I can go for more performance with a P85D or P90D version. My question - am I getting a noticeable performance difference with a P models verses the 90D? I heard the 90D is plenty fast and not much noticeable difference in acceleration. I have not driven them to compare, but would be grateful if anyone has some thoughts on this subject. Thanks!
