Actually, I drive a 1991 Honda Civic hatchback. The back seats fold down, and I can get all my gear in without any trouble. I've owned it since 1996, and aside from a new radiator, alternator, and the usual maintenance stuff, it has been my faithful chariot all these years. For at least three years I spent two hours a day on I-70, but never had much trouble.
I'm a bit surprised about the car rental stuff. We've got about ten car rental stores or dealerships who rent here in town. The airport is pretty backwoods though.
Back on topic, our next gig is playing outside a music store. No drunks, no smoke, and the people who stop to listen always want to know about our gear and seem to care about the music. Not too bad.
