Good timing; I was just going to update this. It seems that whatever glass that is needed can be had for the right price. The standard distribution places turned out nil, but there's stock in Japan, for example.
I think the sweet solution would be an intact parts car, but driveway space is already at a premium. I just got back from central Washington this weekend with a slighlty wiper-marked but intact windshield for my Crown (and the Crown's not even here yet - arrives this week!)
The MS75 Coupe is probably one of my all time faves. The MS55 I've taken on kind of fell into my lap, and we need something a bit more utility, so it was a better fit, but I'd definitely expand the fleet with a fourth-generation Crown some day.
