I hear lots of people talking about pristine non-modded cars being the ones that will bring money. I may be wrong, but the majority of people that mod the 6 do one or more of the following: CAI, pulley, tune, lowered springs, etc. None of these things are irreversible, and I would assume that the majority of people that mod their 6 keep the original parts for just that purpose. I still have all my original parts (to include the original halogen bulbs), and mine could be put back to stock in a matter of hours...... Well, everything but the springs...... Those blame things would take me the better part of a day. Anyway, my point is, I do not really see people doing mods to the 6 that cannot be easily reversed. I have never been a collector, but I do enjoy my 6 and the mods that I have done to her. Am I correct in assuming that as long as I keep the original parts, that mine would not be worth less than one that had never been modded (in similar condition)?
