I would say bad purchase. First, it's new, AND its an unknown brand. I worked in the automotive industry for several years, and have never heard of Snyder. Usually this means the depreciation will be horrific (50% or more in the first year or two), reliability is a question mark, and support for maintenance or repair is spotty at best. If you're a car person, that's no big deal, I drove an old Datsun hatchback in college and the ONLY way to get parts for it was either used off ebay or a single supplier in Minnesota that had a limited supply of New Old Stock (NOS) parts. But if you rely on the car to get you and a child around safely and reliably, it can be a major inconvience waiting a week or more for parts or someone to help you. Another question is safety, I expect this is an exceedingly low-value car, sold in countries like China or India usually, and imported to the US as a "motorcycle", rather than a car. This means it is usually NOT tested by the NHSTA, DOT, IIHS for crashworthiness. And as a motorcycle, it has none. Trust me.
For it's $8K purchase price, you could easily purchase a secondhand Toyota Corolla, Toyota Matrix, Honda Civic, Ford Focus, Mazda 3, or other equivalent sedan or hatchback. I believe a number of Scions are in the price range these days as well. All of these should be reliable, comfortable, and have great dealer network support (as well as private shops if you prefer to avoid dealer repair rates).
Do you have much motorcycle experience? You will probably need a motorcycle endorsement on your license and motorcycle insurance to operate one of these, and the driving dynamics are VERY different than a car. As was mentioned in the previous post, there is a great Top Gear (one of my favorite shows!) clip on the instability of 3 wheelers with a single front wheel, search "Top Gear Reliant Robin". You want the episode where they drive it, not turn it into a space shuttle, though that is an excellent episode as well. While the show is meant to be humorous, it does raise valid points.
I would strongly, strongly recommend against buying one of these. I don't think it offers any advantage over a used car in good condition.
