John, I really think you're better off with Manitop's apparently more reliable car. Mine really isn't set up for long-distance trips: because it has a race fuel cell, there's no spare tire, so I try to stay within flatbed range of home. I do have something called Ride-On in the tires, which is supposed to seal ordinary punctures, but it's no good if you get a sidewall leak or something major.
