I have no rust anywhere else on the car (okay, a couple of tiny nicks), so rust along most of the roofline is abnormal. If it was normal there would be other postings about it.
I took it to one place recommended by Woodfield Lexus (Illinois). They quoted $2000 to replace the roof, and $900 to fix the rusted portion. However, they would not offer ANY warranty on their work... not any!
I then took it to a place called Neat Street that works on luxury/exotic cars. They will repair and warranty the work for life for $680. However, the guy warned me that they need to remove the windshield and there is a small possibility of breaking it when they remove it. He says that they have no idea how much adhesive was used or how easily it will come out. He thinks they'll be fine, but needed to warn me. An aftermarket windshield (not Toyota) is about $500 - $600. A Lexus (Toyota) windshield will be about $800 alone.
This sounds more like a solution.
Any thoughts???
Thanks!
