Originality-does it matter?

Today if I have a very valuable car that was stock/mostly stock I probably would keep it that way. But for me I like driving something that runs good, stops good and handles reasonably well. AC is a plus. Most of my cars are modified in some way. I prefer performance, street drivers. And I drive them in the rain if I have too don't like to, but **** happens. A couple of years ago I had to drive home from Woodward with my Cuda, no wipers no defroster and slicks. Long 60 mile drive. My current everyday ghetto cruiser is an old police Impala all stock but banged up, ran 14.80's with a v6 and each tire and wheel combo weights 70 pounds. Shows what can be done with proper tuning if they want to.
