In my opinion regarding carpet and resale value: Most would not expect that replaced carpets are from the "factory", nor is it that important. But, to get the best resale possible, when you go to an interior shop, just make sure that they use the EXACT same grain/pile/loop that was original. Also, I'd say that doing all of it at one time is better, as fabrics/carpets from different companies wear and discolor differently. That way, it will be uniform all around!

Thanks for the reply. I agree and am going to duplicate the original carpet already in the car the best I can.

The other main modifications that I felt had to be done to ensure a reliable car was to upgrade the fuse blocks and change to MSD ignition (other than some other minor items the local Lamborghini Dealer is handling).
