I'll join in the fun and add Midstates to the list. I bought mine in 1987 and although it has many road scars I have no body shrinkage or warping. My Midstates is as solid as a rock and I wouldn't hesitate about driving it across country right now.
The best thing about Midstates is there customer service. I'm still treated like family after 16yrs. Bob Kallio always asks about me and my family then he asks how the car is doing. He wants the good news and the bad if there is any. To be honest I have never had a problem with it.
Fiberglass that's done right will last forever. If there was a problem with fiberglass then GM would not have used for over 50yrs on the Vette.
In time I will have a Kirkham but I will never sell my Midstates.
