I've been waiting to see what responce he gets, and must admmit that this one made me laugh out loud.
I actually mentioned the dual pane windows in luxury cars. those windows do make a difference. i dont know if there is a market for aftermarket dual pane auto windows, and it would be an expensive upgrade. several thousand dollar windows on a $2000 to $4000 Honda..... no thank you, My 2008 Jetta has single pane windows and i would never consider making such an "upgrade" too much cost IMHO
