So I am replacing my 2008 Audi S8 with a P85+. Just came back from picking up the Model S, and I have to say, Holy Crap!!! The S8 is no slouch, and until this morning, a fantastic and fun car, with plenty of grunt. I had thought of keeping both, but no more. The instant response, the immediate Tesla grin, ... unbelievable. Wasn't sure how much I would miss the Audi, but I have to say after driving the Model S for about an hour, not much. I will give some more direct comparisons soon. In the mean time, need to clean up the S8 for sale. Anyone looking for one?
