LOWERED PRICE to $95k. Poor thing just sits in the garage unused most of the time. I try to take it out for burgers with the kids once a month, but that's about all the driving it gets.

Motivated to sell. Text or call me if you have any questions, 512-560-8176

I haven't read the entire thread. Does the driver's side windshield have a crack in it?
Yes. I have the hard to find replacement OEM heated glass and new seal sitting in a box. Whoever the new owner is can have the it and will need to pay a windshield repair shop to put it in.

The windshields have become pretty expensive. Used to be a guy in Russia that reproduced them but I haven't seen him post in quite a while.
