Still for sale. I am here to listen to reasonable offers!
Thank you!
Not trying to rain on your parade, but since you've had no takers for a while, perhaps you're pricing it a bit high? Have you looked at comparable cars? For example, this one is similar, no ludicrous, but newer (VIN is ~22K newer than yours, but within + suspension production range) and less mileage - $48K from Tesla with 2 year extended warranty.

Now, Tesla only has one P85D for sale right now, so you can also look for comparable age/milage/option cars on the internet. Autotrader shows 43 P85D's for sale:

Another way to find out you car's expected value, call or email Tesla for a trade-in quote - they would list it for ~$10K higher with warranty, so your expected private sale values is somewhere between the trade-in and Tesla list price. Can you sell for more? Perhaps, but it's a gamble only you can choose, risk your car depreciating more for a chance to sell it for more.
Good luck on the sale!
