Options add to the cars value, they don't reduce it!!

The title to this post seems like a no-brainer, but you'd be amazed at the heated arguments I've heard from people regarding adding options to cars that didn't originally have them. I'm not talking radical changes-like stuffing a Hemi crate motor in a Dart ( what's wrong with that? ) to build a clone of something you could never afford.  No, I'm talking adding trim pieces or other stuff that was available as a factory option on a particular car, but yours doesn't have it. Let's say you have Z/28 Camaro. But it doesn't have Rally Stripes. Or a Trans-Am without the big hood bird.  By adding the bird or stripes have you hurt the car's value, really? Or what about wheels? So your T/A came stock with Rally II wheels. If you like the "Smowflake" style better, put them on. What is hurt by that?  If you want a "Go-wing" spoiler on your Cuda or Duster, or a "Bumblebee" stripe on a Charger or Challenger does it "ruin" the car?  If your Mustang needs a new interior anyway, and you want to add reproduction "Pony" seat covers, what harm is there in that?  This you can't change a thing, because it will compromise the value crap has to have a limit. Are we car guys, or stockbrokers?  Does everything have to be geared to getting the most money when you re-sell it? If your not going to drive it or show it, and all your effort is geared to try to sell it for a huge profit, then why buy it in the first place?  If that's the case, don't you think adding options would up the price?  Why sell a 440 Road Runner for $20,000 when you could spend $2,300 on a Six-Pack setup and get $30,000 for it?  The same goes for paint. Don't you think a red SS Chevelle or GTO will bring more money than a drab brown or Olive Green one?  Even if the color isn't "original?" I've said it before-anyone who even thinks of cutting up the trunk of a Hemi Cuda for wheel tubs ought to be dragged out into the street and shot, or my personal favorite, entrails cut out and burned. But you did not "ruin" a 66 GTO because you scrapped the 4-barrel and installed a tri-power setup you bought off E-bay!! Mastermind
