I don't consider taking arguments to an absurdity as proving a point. Besides, the dimensions are in the contract. You bought a Model S - that's right in the contract and it's easy to prove what the dimensions of a Model S are without being concerned about the parol evidence rule.
Again, however, I never said anything about "having a case" or not having a case. Clearly, there are grounds for a case. The issue was whether that case has any doubt. I see no doubt if you got a miniature car. How they got the 85kW battery in it is another issue since that is in the specs...
So, the miniature car scenario, no doubt you could win a case. Let's take it to the other extreme. Let's say the cup holder can only hold a kids juice box. Okay - probably don't have a case.
The mini car - blatant false advertising. The cup holder, not so much. Our scenario with the range issue falls between those two. Where exactly that falls is somewhat subjective, and I understand your point about there being at least "some" doubt. But, we're talking about a feature of the car that no doubt heavily influenced people to purchase the car. Somebody on here said they chose the S85 because of the range issues. That is a perfect example of how some early P85D folks would have made a different choice with accurate information.
Just a quick search on false advertising... Has 5 things for proof of requirement:
1). False statement of fact has been made about the goods or services. Check.
2). The statement either deceives or has the potential to deceive a substantial portion of its target audience. Check.
3). The deception is also likely to affect the purchasing decision of its audience. Check.
4). The advertising involves goods or services in interstate commerce. Check.
5). The deception has either resulted in or is likely to result in injury to the plaintiff, usually attributed to money the customer lost through a purchase that would not have been made had the advertisement not been misleading. Check.
Again, maybe you have a differing opinion about the severity of the issue which gives you doubt concerning the legality, but as an owner of the car, there is no doubt in my mind this whole debacle is grounds for legal action.
That said, I've never returned anything in my life... So I'm not planning to rally the troops and storm the castle. I honestly don't really care that much about clawing back a few bucks. But if somebody else put something together and a paper made its way to my desk, I'd sign up based solely on giving TM a swift kick in the ass.
