I was wondering if you think I should leave the center fog grille on or replace it with the stock grille when I (really) try and sell my car? With and without~ Will the person factor this in on buying the car?

 

Put the factory grille back in. You can sell the center fog grille for some amount of money.... or you can show it to the potential buyer and have them buy it from you. Some people don't like the center grille, may as well play it safe.

my 2 cents

 

give them a choice

 

+2 on giving the buyer the choice.

 

Well I'll put the center fog grille on the for sale section and if someone buys it then my decision will be made.
