If you ever want to sell the car you will need to take a grand off the price for the wrong seats. I myself if looking at a car and notice they put the wrong seats in will walk away and not even think of buying it.
Your car NEVER worry about what somebody thinks about if unless your a flipper.
I would not invest over a grand in the original seats, they are not very comfortable
and made of cheap vinyl that does not hold up. However don't throw them out as
he pointed out some don't go for the non original look,as to include if you sell.
