"Must Have" decals
 

I just got a set of these on eBay and am extremely pleased with them. The look is JUST LIKE etched glass, even up close.
And the price is great, less than $8 delivered. Just put mine on today, but didn't get a pic before dark. I put them on the quarter windows.

Now you need one that goes on the driver's side mirror and says, "Objects in mirror are losing!"

Got one! THAT was my other eBay purchase that day. I cut the Ford logo off because it looks better without. I get a chuckle every time I look at it. :p
