How original have you kept yours and why

Other than going with Kelsey disc brakes, 8 3/4 rear, ralley wheels, 150 MPH speedo, oem clock, and color change my car is going to be equipped as original.
It is a 68 Barracuda convertible with power top, power steering, power brakes, 318, auto, console, bucket seats, sway bar and ralley wheel covers.

Everything I am changing will still be factory options for the car execpt the ralley wheels and maybe the color. Still thinking about the Plum Crazy Purple, if not it will be red.
