Aftermarket accessories can make or break a car. In this case, they break them. You sent us many great suggestions, but these ten are the worst things you can put on your car.

10.) Rear window louvers

It's cool if you happen to have a Lancia Stratos, an Opel Manta, a Mustang Cobra II T-top or something equally cool from the late seventies, early eighties. But when it comes to modern cars, just grow up.

9.) Baby On Board

So what? If you don't have a baby on board, I should feel free to crash into you? It doesn't make any sense.

3.) False badging

Don't try to make it look more than it is. There's nothing wrong with a V6 Mustang as long as you don't fake it into a Schnellby.

2.) Aftermarket HID headlamps

Blinding others on the road is unsafe at any speed. What you deserve is something like this, on both sides:

1.) Truck nuts

Lost your own? We don't want to know.
