Driver's side door, where the VIN is. The sticker there has a manufactured date. It's just month/year, but if you got it early in the month, then you'd expect its manufacture month to be the previous month. If it's 2 month's old, it was likely a reject. If you got your car at the end of the month, it probably should have been manufactured in that month. If you get it in the middle of the month, then the manufacture month should be the previous month, so it's possible it was a reject that was quickly fixed, but since most body shops take a while to do the work, it would be unlikely.
