DO NOT LEAVE THIS IN YOUR REAR WINDOW WHILE THE CAR IS SITTING!

This product is made of a thermoplastic, meaning it can warp in heat. I've only had this happen once, in 90+ weather, in the sun. In this scenario, it will warp. However, I've done an 800 mile drive in 90+ weather, during the day, and I'm still currently using said spacer right now (as of 2 months later).

BUT SINCE THIS LEAVES YOUR WINDOW OPEN, DON'T LEAVE IT IN IF YOU ARE NOT IN YOUR CAR! I AM NOT RESPONSIBLE IF SOMEONE BREAKS INTO YOUR CAR FROM YOU LEAVING IT IN!

A spacer for the rear window on a Smart 450 or 451. If you own this car, you know how annoying it is to have your windows down. This reduces the turbulence and sound dampening that happens when the windows are down, and makes it a much more enjoyable ride.
Color will probably be black, but color will vary as it's made to order.
