Non Matching seat..Any ideas

Looks to me like a recover. may have even replaced just the center panel.

Special order is all the more reason it would get a generic cover replacement if the upholstery was damaged, the dealership would've had very little time to find a proper replacement, it could've been damaged on the truck during delivery and replaced as soon as it got to the dealer, I believe some raptors have been on delivery trucks for up to a week, a lot can happen in that time, unless the previous owner was at the dealership when it was delivered and kept an eye on it the entire time it was there it's very possible it happened that way, and there would be a very high likelihood of a situation like that not being recorded in the repair history
