i testdrove a tesla model s two years ago and walked away mostly because of the poor build quality and lack of high end power. the car has torque but lack of horsepower. just look at the quarter mile trap speed and it is significantly slower than the competitors such as E63 or RS7. Handling is awful too because of the battery making the car heavy... the build quality is just like other crappy american cars...
RS7 handles better than Model S P85D
The newer P90D can't even beat a S7, remember RS7 is quicker than the S7
The problem with P90D is the battery couldn't supply consistent energy to both motors. That mean the car is not even fully developed and already being sold in the market for the idiots.
In a nutshell, only people who don't know cars will buy Tesla or any electric car!
