Sun visors that block the sun, front and full length side. Should slide out and extend full length of the side window. Just like an Equinox or C/K.
Harmon Kardon or similar top quality sound system.
V8 auto trans with no AFM.
Keep the retro theme going, make it even more like a '69 Z28.... hideaway headlights, hounds tooth,
A little smaller, a little lighter.... but a hair more side window height, less roof chop. This will make using an ATM possible, and still look like a '69 Z.
Factory tint on the rear windows.
A couple real sweet blues like IBM and ABM.
Fascia suppliers that can match the front fascia to body color perfectly or have the plant paint the whole car. 2 cars in row for me, front fascias not even close to matching the body color. Yes, an old issue, but unless addressed will be a new issue.
Dirt nib free paint.
