Mismatched Vin Numbers

[BIGJake111]

I noticed an add anomaly today when adding a porsche a pen with the owners manual and books. I noticed that the vehicle identification sticker inside of the cars service log (just like the one on the underside of the hood) was for s different car! The book is full of stamps from the dealer that is also listed on the window stickers, which the vin on the window sticker matches the vin on the car itself.

I just found this odd, any speculation for why there is another vehicles sticker in my service log?
