The top - the top layer is about 4 years old. That spot at the top of the window is concerning. It's not torn, but the fabric pops out from under the rubber seal when it's folded down. The middle layer and the headliner willl definitely need to be looked at and eventually replaced. The frame itself... not sure. It does take a litle bit of effort to put it up/down. If I'm lucky, maybe just a little bit of lubricant will fix that (if it's even recommended). Since I'm in Vegas, I'm not super concerned about the materials at the moment. So little rain (and the car will likely never go out in the rain) I figure that's a "down-the-road" item.
I've noticed a lot of the rubber seals around the windows (against the body) are going to need replacing. 37 years old and I'm surprised they are not MORE dry-rotted than they are.
The speedo wavers a bit at speed. I did notice a little bit of wavering while driving - so I'll have my mechanic look at the fuel filter and pump just to make sure they are good.
Struts will definitely need replacing. Bouncing the front end up and down clearly shows way too much softness. They very well could be original.
As far as the interior goes - the carpet looks good. The seats - at first I was thinking just the material would be replaced, but after driving it home, I can tell the cushions are dead. Also, whoever put the aftermarket radio in cracked the dash surround. Not a priority, but eventually will try to replace that.
After the car has been sitting in my garage overnight, I've seen absolutely zero fluid on the floor - so I don't think there are any leaks to be concerned about. (I know... just 8 hours probably isn't enough to be definitive on that).
The wiper fluid not spraying... I can't believe I didn't notice this before, but the hose isn't connected to the nozzle on the hood. But I'm guessing the wiper motor has to be replaced anyway - the wipers themselves move VERY slowly. (Will have the mechanic look at the electrics, too, to make sure there isn't a unknown major issue to deal with.)
When I pulled into the garage and shut it off, the fan did keep running, so I'm happy about that.
On a funny note... after having my Golf R for two years, it sure took a bit of getting used to non-power steering and brakes.
