I think I'd be in trouble if I answered anything but purist with my car. lol.
though I have considered a few small upgrades to make it more reliable/comfortable...nothing that could not be easily put back though. I had considered disc brakes when I first bought it, but after driving it, I find the power drums are plenty adequate, so they will stay. Other things I'm considering are Pertronix and a modern hidden stereo so the original one stays in the dash, but I've got some work to do before I get to those. Gotta get the clock and cracked steering wheel repaired first. I will be keeping the original movement in the clock though.
