The big thing is that top & windows aren't fully functional. Several other little things like the radio, clock and fuel gauge don't work as well.
Oh, and you can see in one picture there's a weeping soft plug that needs attention. Most were replaced last year, but there were a couple that were hard to get to that haven't been done yet.
The front bumper and other trim chrome is not perfect (rear bumper was redone years ago and looks great) and there's a small rust spot over the rear plate, but he's not after a perfect show car. The interior cleaned up well, but still isn't as good as the exterior and might need some attention eventually.
But for driving and enjoying it, it's really just the top & windows. This car has been in a garage, sitting, ever since I can remember (probably 40 years). It was very good to see it out on the road again.
