When I spec the Model S as I want it - it is very close to $100k. I can find a very low mileage (<5000) '13 BMW M5 for upper $80's. Really like the p85 but M5 has more content (HUD, range, track capable, luxury items, etc.) and is slightly more proven. Hard to say which is more fun to drive. I really like the new P85 tho - and would like to say good bye to gas stations and all that is behind ICE transportation solutions. Truly would have to reprogram my brain to learn to love the lack of a hi performance exhaust note. I thought the bimmer would kills the Model S on cost of ownership and it obviously does in fuel - but the $600 a year is a bit of a pain given I drive only 9k a year. BMW provides zero maint costs for 48 months. As cool as the M5 is - P85 is cooler. AND has less porcupine effect (compared to BMW). Have really enjoyed reading comments on this board - very articulate and pasionate group.
