I would definitely suggest getting a spare and not relying on the compressor fix a flat contraption chevy offers by default. With smaller tires as the spark has they don't take pot holes in Michigan all that well. I just recently blew out a tire leaving a sizable gash which couldn't not be remedied by the fix a flat solution. If I do get a spare I definitely want the spare and jack to fit in the space under the carpet hopefully this will be possible.
