My VIN also changed from a G to an H, S60 for "late December - January" delivery.
I did have the following thought: for resale, having a 2017 VIN may be beneficial. However, in Connecticut, we pay property tax on our vehicles, and I'm wondering if having a 2016 VIN may actually be better (financially)? Here's my thinking: property tax is based on the value of the car. If I get a late December 2016 VIN, come January that car is "one year old" and will almost instantly be depreciated for property tax purposes. I think they can only go by year as they use the VIN for tax assessment, and can't tell the month it was built, I could be wrong on that, and if I am wrong that would obviously negate this math. Conversely, a 2017 VIN would be "brand new" all of 2017 and be assessed at a higher value. That depreciation game would continue every year, since the 2016 car would always be a year "older", so the savings continue every year.
The cars would be the exact same, physically, just one would be a month older, but on paper one is a year older than the other. From a net present value perspective I think those property tax savings probably outweigh any resale value benefit. I.e., I would've preferred a 2016 VIN. In addition, delivery in December would've resulted in a Net Present Value benefit on the tax credit as well, since now I'll have to wait a year longer and cannot earn a return on that money yet. Doesn't change the fact I'm stoked to get the car
