Hi everyone, I just signed up here so i apologize if a similar thread exists.. but i am very close to pulling the trigger on a new model s 75D. I currently have an Audi Q5 with just under 60K miles, and its completely paid off. Its given me no issues whatsoever, so i really dont need to get a new car. However.. i started a new job about a year ago and found out we offer free electric vehicle charging in our parking lot, so that is vasiclaly $100 in free gas each month. I always have wanted a model S so after doing a test drive and playing with some numbers, i have gotten to this point where I am just looking for some reassurance that spending around $50K for a new car is a smart decision. My justification for it is pretty simple: I spend the $50K over the next 6 years to get a car that should last me at the very least, 15 years... I put maybe 10K miles on a car in a year, and hearing that most tesla batteries maintain like 95% of their charging capacity after 150K miles, i'm led to believe this car should run beautifully (knock on wood) for those 15 years. Then after i reach whatever the battery threshold comes out to be where its time to replace it (does anyone know this milleage # yet?), i'd just cough up the money to get new batteries, essentially giving my model s a new life. Have I done my research on this enough? Or am i misunderstanding how this should work. I just want to make sure that me getting off of a car in which i owe no money, for an expensive electric car, is actually a SMART decision for me... especially while my Audi has some value (i've been told its worth about $18K). Looking for some feedback. Thanks everyone!
