The bad.

One piston skirt is worn out pretty bad. It sounds like a rod knock, but to a keen ear it doesn't fit all the symptoms. I measured the clearances in the bottom end they are well and bearings were replaced. I've driven a few cars with skirt issues, it just makes noise as far as I've known.

The fix is pretty simple, the pan can be removed while in the car. Pop a piston and rod out, replace.

Front windshield seal is coming off in a corner. looks like water could get in there.

Sunroof broke out... big bummer, but I cut a lexan replacement, i have and will include some special tape for it, I would say replace the tape every year or so. I just pop the sunroof out when I drive the car.
