You can get more than a guitar in there!

Roland A-37, Korg Triton LE 61 key, Roland D-50, Roland AX-1, a Roland KC-550 amp, Keyboard Stand, 2 accessory cases for cords and pedals, a 2 space rack with a Peavy Deca-700 amp, 2 PA speakers - 15" Yamaha's, 3 folding stands, and 2 sets of those furniture dolly's to haul all my gear

You can fit an amp, ladder, surfboard, and 12 2X4's. Wait...nevermind, I was thinking of the Dodge Magnum.

 

I fit this in my HHR. I even have room for my girlfriend in the front passenger seat after my kit is all loaded up. Man I love my HHR!!
