That’s a great price for a great scoot. I wouldn’t worry about the warranty as I have rarely seen anyone use it. As long as the gas and oil is fresh, I wouldn’t worry about it sitting for the past few years either. It more depends on how you want to use the scoot and if looks is a big consideration. The Like has a classic look and is a bit higher tech (LED headlight and ABS). The Smax has more power, 10-15 mph higher top speed, and more storage space (the best in the 150 class).
