It tough to figure out, Tesla keeps adding options like the the new Matrix Headlights (PLAID Only), new taillights, etc.
Simple rule I use. Minus $1 for every 1 mile in mileage, minus $10K for every year of age, you are fortunate that your mileage is so low, your sales price should be around whatever you paid (X-Mileage-(current MY - your model year) -$10K = price)
I have bought both my current Model S's using this formula and works pretty well until you go past 4 years 50K miles.... then it slows down a lot... I have one Model S with 88K and and another with 130K, but they are valued about the same, because one is a P85+(rare) and the other is 90D...
You should get close to 100K in the National Capital Region, lots of buyers here. Without more details on options, full range charge, in service date, etc. its hard to tell...
I personally won't buy another S, until they bring back the PANO sunroof, those new headlights are nice, but the older Model S's have horrible headlights, I have the Bi-Xenon, and they are good, but the Matrix Headlights are far superior, and being close to the 4th quarter age wise, I need the best lighting I can get.
Good Luck with the sale, this is a nice looking car, if I were in the market, I would pull the 21's off, dump FSD, and get the price as competitive as possible. Price goes down, range goes up, but it personal preference... I am weeks away from getting
carbon fiber wheels after waiting almost 4 years, and might jump to the Plaid anyway....
