I also purchased a fully loaded 50d minus the 4 zone, as I never have more than two people in the car.
As far as resale this is something that won't be affected when you decide to sell.
My stealer had said out of all options to help the resale value, the third row seats were the most cost effective - even though I opted for these never use them.
