I got some sticky red/white reflective tape
like they have on the sides of big rig trailers,
cut out the white, and stuck it on the back of
the van.  I'm sure I reduced the van's value
to $5999 right there.  Also put some on the
inside of the driver's doorjamb so it shows
up when you open the door.

(night time is VERY impressive -- you can see this stuff
three blocks away!)
