My fast and smooth '13 S6 has been replaced by this:
a 2018 Tesla Model 3 Dual Motor Performance, aka M3P (with apologies to BMW...)
It was delivered on 12/28 (yay $7500 income tax credit!) and I can already state unequivocally that it's the best car I've ever owned.
First time in 20 years that my DD isn't an Audi, but I don't regret a thing.
Happy New Year!
