Luckily that polling has already been done several times, I believe you lose.
"
After averaging national pricing data, the report said owners paid an approximately 80% premium on their Tesla cars compared to the average selling price of their previous cars....The results also showed that if drivers had not purchased a Tesla some would have rejected going the luxury car route and instead bought a car with an average selling price as low as $30,000, once again indicating the high premium drivers give Tesla. Of those surveyed only 13% of respondents said they would have purchased a vehicle with an average selling price higher than the Tesla Model S, which begins at $75,000 for the 70D version."

Well, thanks Drivin, for proving I'm not crazy. I really didn't think most Model S owners were considering the 7-series or S-class when they made their buying decision. It seemed like a mix of Prius/Volt owners, mid-range German car owners (5-series, E-class, A6...M3, C63, etc.) and very few 7-series/S-class people.
It's a particularly odd comparison when you consider that the only way you can get a Model S to cost as much as a well equipped (real-world) S-Class is to buy the P90D. The kind of person buying a P90D is buying it for the performance, with "luxury" being secondary. If you're considering a P90D, you're likely cross-shopping an M5 or E63. You choose the Tesla because the tech is awesome,
maybe because you care about the environment (feel good), and mainly because it does 0-60 in 3 seconds. I don't see that person cross-shopping boats like the 7-series and S-class.
Then on the opposite end of the spectrum you have the 70 and 70D people, who are certainly not cross-shopping $100k+ Mercedes with their $60-$70k (after incentive) Teslas.
So the goldilocks 85D/90D people in the middle with $80-$100k (after incentive) Teslas are the only fair comparison, and even then, I doubt half of them cross shopped the S-class. I know I didn't. If I didn't buy the 85D I was seriously considering a C63 or Jaguar F-Type (yep, want to talk about apples and oranges? hah)
