My Syncro Westy had tinted windows when I purchased it in 2001.  I
had never had tint in any of my previous buses, but I immediately
liked it.  Privacy during daytime plus less heat load for the
AC.

After about ~8 years, it started turning purple.  The tint person
that I had dealt with said that older, earlier films would turn
purple, but newer ones with metallic tint rather than dye would
not.

After I couldn't stand the purple any longer, I had her strip the
old and install new tint.  It has been there ~2-3 years and
is great.  Check back in ten more years....

I should add that my Vanagons are parked outside at 5,000' where
there is more than enough UV!  My '81 without tint is suffering--
the vinyl seats.  My '87 with tint has a beautiful interior still.
