I'm trying to make a decision about reserving an X based on the info that we have about the car so far. Part of this decision is a consideration of when the $7500 rebate is going to expire and when the X I want can be potentially delivered. I know that the part of the rule for the rebate is that producing company has to deliver 500K vehicles in US after when the rebate expires in several phases. But I also heard several sources on the Internet saying that it is going to expire in 2016 regardless of the cars produced so far, however I was not able to get a document source to support this claim. Does anybody know that the 2016 is the expiration year for the rebate or 500K vehicles sold in US is the only condition for this rebate to expire? Thanks in advance.
