Saw a 420 SEL the other day. In fact I was trying to buy it before I found the 560. I noticed the rear defrost had rather thick, ugly copper lines in the window.

Mine has lines so thin that I did not even think I had defrost! Just a switch to look at.

What was standard? Was the thin wire normal or an upgrade? Was it only on the 560? Did the 420 simple have a new window installed?

Just curious.
