If the guy is really selling it because he thinks the back glass is impossible to find and does not know reality, then IMO it would be unscrupulous to try and purchase the car without him knowing that. That's just something I would not do. I cannot honestly believe there are members here actually encouraging this. Makes me ashamed of some of you. You should be honest with the guy. Then if he sells, it will at least be with him knowing the truth. How would you like it if someone did that to any of you?
