Are you sure there is no spare - that sounds unreal. I know that a while ago they moved the spare to under the drivers seat where it was almost impossible to get at. Whoever had that idea ought to be fired along with the guy who decided to put the battery on the Sebring/Chrysler 200 convertibles under the fender instead of in the engine compartment. Last time I had to change batteries when travelling they overcharged me for the battery and then charged more than that for installation.
