What?

What is the strangest, or most useless, or coolest accessory you've ever had on a car you've owned, or seen on a car you've ridden in?

I had a Ford Taurus that in addition to having a digital clock in the radio/cassette console also had a digital calendar. It used to come in quite handy.

My sister and my brother in law had a heavily customized Pontiac Bonneville when they were first married in the early 60's that had a record player in it, which was actually pretty useless. At one time they also had a Chevy Impala that had a horn button on the dash on the passenger's side. I bet Jonnie and JohnnyC would have worn that sucker out.
