I did not get the upgraded sound - very disappointed with standard sound - not sure if upgraded is that much better
Well, we've had three of them so far, and driven several service loaners, so here are our observations:
1. Our 2013, a summer build S85 had: 21" wheels, Studio Sound, Tech Pkg, Air Susp, and cruelty-free Textile Seats. It was lost to a flood but we loved it, only wishing for the many options that came out later (folding mirrors, Parking Sensors, etc.). No Pano roof as I've driven far too many that squeak and creak--why pay extra for hassles down the road? It was replaced with:
2. P51691, one of the last S85's built withOUT the sensor suite (but with the new steering column). Tesla had massively increased the cost of the options so we left out the sound system upgrade ($950 to $2.5k; REALLY?!?) and the 21" wheels, but we added the parking sensors and fog lights. Wow, I had no idea that the base sound system could be soooo unbelievably bad! Granted, it might have just been our individual system, but it could not even play talk radio without cracking sounds coming from the speakers. Our local service center never fixed it (nice guys all, but oh so overwhelmed with service and delivery cars for the entire DFW area), so after 4 weeks, and being bent over by Tesla on the trade-in value, we traded it in for a now "on hold" S85D, or perhaps a P85D, depending upon when Tesla gets its act together vis-a-vis the NextGen seats. (We don't think destroying the environment, and blowing the brains out of sentient animals to sit on their skins, is acceptable, but would prefer the NG Seats, so we'll wait.) Oh, and it's not like this is new news--try this UN report from 2006 on for size:
Livestock a major threat to environment
Also, in comparison to the 21" wheels, the 19" Michelins on this car felt terrible--like it was driving on a wet road ALL THE TIME. Couldn't accelerate without the traction control light going crazy, and as for stopping--best to call ahead and make a reservation. How do you folks with 19" wheels tolerate such lack of grip? Oddly, I think it's just a function of the different tire footprint orientation, and taller sidewalls, but oh, what a difference. Car and Driver has a data point for us with their recent test of a S60:
Tesla Model S Reviews - Tesla Model S Price, Photos, and Specs - CARandDRIVER
"Stopping distance from 70 mph, however, increased from 160 feet in the P85 to 174 in the 60."
That 14' felt like a mile on our S85....
3. To tide us over until Tesla gets its act together on our 2015 P85D (or S85D) above, we found MS #3 on eBay: a 2013 P85 with very high miles. Studio Sound is back and it has 21" wheels, so that's good. What's not good is that the seller was VERY selective with his eBay photographs, and failed to disclose significant impact damage to the front of the car, even to the point of hiding it, as suggested with some peculiar use of glue to attach the front fender liners to the core support. Nice! We're now having to use eBay's Vehicle Purchase Program to see what they'll pay for the repairs as I type . . . what an asshat.
So, the only regrets are that:
A. Tesla works to save the environment with one hand, while helping destroy it on the other, by not switching from using murdered animal parts in their cars.
B. Tesla doesn't make the standard wheel at least 20".
C. The base sound system is so atrocious.
