I brought a black/black MS from OH over 5 years ago. I have had the windows tinted. We also purchased a 2022 MY in white. We sense no difference and the fact that you can pre cool the cars is a plus.
I'd say get the car you want. IMHO color doesn't matter that much. Certainly black absorbs more heat and one or the other color may be more difficult to keep clean. I take it to the car wash and am not concerned about looks. Everyone has their own idea of what's important. My wife loves black on black but we thought white might be good for FL. As I said: we don't notice an appreciable difference.
As there are strong data to the contrary to this poster's comment, "We sense no difference . . . " I would suggest that their input, while interesting, is also not supported by any facts.
Until it was stolen by an HVAC repair technician, we had a laser remote thermometer from Harbor Freight. It indicated a very large temperature difference between black and other colors on identical cars parked in the sun.
To duplicate this yourself, without equipment:
1. On a hot and sunny day, visit a Tesla gallery at early- to mid-afternoon.
2. Find identical Teslas parked facing the same way/orientation.
3. Place your hand on an exterior painted panel of a white version of this Tesla.
4. Count how many seconds you can leave your hand there without debilitating pain.
5. WARNING: this step may result in SERIOUS BURNS. Rest your hand on the same exterior painted panel of a
black version of this car . . . .
Yes, exterior panel temperature is a proxy for other temperatures, but you get the idea. Please let us know the results of this experiment where you live.
A single data point, but worthwhile nonetheless: We have an inventory-purchased (as in, "not our color choice") MSM/black Model S Plaid in Arizona. According to the Tesla app, on a sunny day with ambient temperatures of only 114F, the interior temperature can reach 168F. I'll check again when it's 120F+ to see by how much we'll exceed 170F.
In closing, this poster's comments notwithstanding, white remains a far, far better choice in warm environments like Florida.
