With HW4 and Radar v2 out, this is going to be a tough sell anywhere near the asking price. The mods are great, but it's all about the tech for Teslas. The are lots of Tesla owners that upgrade to newer models as often as they upgrade their phones and other tech devices.
On top of that, Tesla continues to drop prices on brand new cars that have the latest hardware. The market conditions are horrible for those who acquired their cars over the last 2 years, paid much higher than the current market, and are now trying to sell.
With regard to criticism of pricing on forums, while it may not be proper etiquette, much of the negative comments might reflect the views of many others that don't bother to post for the sake of being polite.
If it were my post, I'd rather have posts that criticize my listing (though they may hurt my feelings) rather than zero replies and no feedback whatsoever. It's highly unlikely that a potential buyer out there is thinking, "Darn I was going to pay this guy $129k for his car until I saw another post saying his price was too high."
