I am currently in a 2014 Model S and looking at a very low mileage inventory car from a SC in another state. I am in an area without a showroom, so it isn't easy for me to go test drive vehicles and compare. I love my Model S, but I have noticed areas that I hoped would have been able to been improved on. For example in my 2014 I still have quite a bit of wind noise which was improved but couldn't be fixed, as well as a lot of front motor whine, among other things. For those that have owned a prior year and new Model S have you really noted improvements in the fit and finish of the vehicle? Thank you.
