Re: 198,000
"it's like saying the ferrari F12 berlinetta is one hell of a car, so this fiat 500 must be great too."
Not sure what you are trying to imply there as the Fiat 500 is a great car for what it is designed to do. Whilst I wouldn't want to take one anywhere near a motorway, they probably have the Ferrari licked for a day-to-day town-center commute or shopping trip.
Whilst I agree that the quality of previous Tesla cars doesn't necessarily mean that the new one will be as amazing, they have done enough impressive stuff to deserve a little faith.
