Vetting a Formula S

If they are there and match the last eight characters of your VIN, the engine and/or trans are probably original to the car. I've heard of people restamping the characters to fake it, but that seems to be something done on high dollar B and E-bodies.
To some these numbers mean a lot, and to others nothing at all. But I think I've heard they are worth a 10-15% bump in the price of the car. It's up to the buyer if it's worth it to him or not.
to me, the rarity of the vehicle plays an important part of the whole numbers game.

like if i was gonna buy an M code car it would have to have the #'s matching motor and trans. the same for something like a survivor car or a "1 of [***]" piece. that, to me, is what makes it special and unique.

on an S car, non OG numbers but correct pieces would be acceptable with that type of 10~15% adjustment. again, in my personal thinking. it wouldn't be a deal breaker, but the number could move the needle either way if i was on the fence.
