Time travel, exactly what it is. You nailed it well Shaun.
Those old cars are an era, a point in time- No point in having an old car just to bolt in all modern stuff, just start with a newer car. I spent nearly as much on my Qjet getting one custom built as I would have on entry level EFI just to preserve the character of the car and increase power and reliability.
I believe modern trends like pro-touring will be the "corvette summer" and disco van of the 21st century in a decade or so, not to mention in most cases the current fads (poly bushings and billet suspension this and that, coilovers) make the cars nasty to drive and unlikable and in the future, worthless.
But they sure
look cool..
