So, I just noticed that my preowned 2013 Smart was missing the tire pump and the sealant was expired. After pricing the pump and a bottle of new sealant I decided to find an alternative. I bought the Slime Smart Spair kit on Amazon for 19 bucks. It includes a bottle of Slime, which I have used in the past with great results, and a compact tire inflator with gauge. Just trimmed the sealant well for the larger bottle of Slime and placed the inflator fit where the original one was. Just throwing it out there for anyone who wants a cheap and easily replaced kit for their Smart.
