Earlier quoted context omitted.
It’s lying because it’s not an apples to apples comparison. You can buy a similarly equipped Honda Accord for $10k less without all of the Tesla drama.
I really doubt the Accord would have the same acceleration or features as the M3. And it consumes a decent amount of gas which is more expensive than volts. It's more of an apples+cart comparison. It seems shady because they can't know what kind of car you're coming from - so they average it (in their favor).
The federal government even publishes per mile total costs for most vehicles that makes it fairly trivial to do.
It’s a bullshit metric. They could honestly present the information in a way that looked good for them as well... or even use it as a cross sell for solar.
