The problem is exactly that, you don't know.
The cost of the service contract is nowhere on the Tesla site except buried in a response to a blog post. If it were up front in the price, there'd be no question of what the cost was.
Then there's the issue of what will the 5 to 8 year battery warranty cost. Since Tesla seems to have a policy of charging for "included" items and notifying people only after purchase, aka "bait and switch", there's a real question of what's in store.
ok, come on - now you're just passing misinformation.
Service | Tesla Motors
that is NOT in any way "buried in a blog post"
but that's really not the point - i get that people are upset that we (and i include tesla here) didn't know up front what the full price was going to be for service (and for supercharging in some cases), and we still don't know the extended warranty.... these are early adopter issues. It's not bait and switch. it's tesla publishing information as they have it - and yes, that sucks for some early adopters, but such is life in that scenario.
In 6 months or a year, these will all be complete non issues. people who are signing contracts at that point will know exactly what the costs are, and I for one think it's much better that they break out costs to this extent as opposed to having everything just hidden in the base cost of the car.
