Hi, Scala,
I understand completely your conflict, and think that you should follow your dream. You can have it both ways.
My first restoration was from a purist's point of view. I restored a '69 Ferrari authentically to a prize-winning condition, then sold it because it was no fun any more. It was too perfect to drive! An hour's drive would result in a week's work to make it clean, scratch-less and pristeen again.
My current restoration (almost finished), is anything but purist. It's a '66 MB 230SL, to which I've added A/C in a console of my own retro design, along with a backup camera and monitor, and a front camera in the grill. I got tired of bumper dings. The car also has wide white walls, a modern four channel retro style stereo radio with CD, USB and aux input, Garmin GPS with voice controlled everything, including hands free telephone, a flip-up wind breaker, cruise control and an upgraded 55A alternator.
All of the above are because I'm getting to old to care about purism and my wife doesn't like old cars, so I'm making it as luxurious as possible so she will use it with me. I plan to drive it six months per year until
it dies or I do.
The only concession I made was to save all the original parts and to make no irreversible modifications.
As we used to say in the auto industry, it's only sheet metal. Do what you like and enjoy it to the fullest.
Have fun!
Tom Kizer
