Mine would be my Android head unit. Remote start is pretty high on the list, but I don't use it nearly as much as the radio. 700+ songs on a microSD card is a wonderful thing.

 

Trailer hitch. It's saved me $30,000 by not buying a pick-up truck. Better yet, by disconnecting a plug, two chains and the coupler I've got my Patriot back. I only need the trailer a few times a year -- once a month at most.

 

Sad.......my Rugged Ridge floor liners. These things are marvelous, especially during the messy winter months and all the nasty slush, etc..

 

They are pretty great liners. I wish they just sold the name tags for them, one of mine broke off while being cleaned.

 

My favorite thing is... ME! And that's no joke.

 

Scan Guage II

 

Definitely the Air Horn
