still nope. it's way cheaper to stick white vinyl over the existing window (from the inside). rather than have it taken out and replaced with a metal panel.
it's also temporary which will not reduce the resale price of the car.
Used to be the 1st thing done to all my vans, before I started buying ones without glass, was to "blackout" the back windows, sometimes just with some plywood
the reason was to stop dirty, would be crooks from seeing any tools or valuable stuff in the van.
The 1 way glass is a good idea IMO security and some rear visibilty also
I wear a top line hearing aid, I swear, if you write on a piece of foil and put it in a microwave. (Remember to put your ear up to the door).. you can hear what you wrote.
