Hiya - congrats on the excellent purchase! Am sure you'll enjoy it!

I'e seen the eTron but never driven it and I must say it does look quite stunning! The interior is quite plush too and I can totally see why you'd go for it over the Model X!

I am much more a fan of the Model S and don't really like the X, to be honest - find it too "fat" and just unweildy. Also not a fan of the doors!

What was the price difference between the eTron and X? The only thing that I'd say is a big differentiator are Tesla's excellent Autopilot and Supercharging networks...not sure if Audi's is on the same scale but it's certainly a better car than the Model X IMO!
