You must've gotten really lucky or else the people I know are the exception.
Some friends of mine had 2 brand new Bayou 220's back in '97, they had nothing but trouble with them. One they rebuilt the engine 3 or 4 times, I don't know about the other one, but it wasn't a decent machine by any stretch. They also had to go to the dealer constantly for carburetor problems, the needles broke among other things.
For some stupid reason we got a new Bayou 220 in '98. It never ran for snuff right from the start. It won't idle for anything, turning the idle up didn't help. Fast idle when the choke is on works. It very often dies when going from neutral to first gear too. For some stupid reason it's still around. Still works and rides too. Pain-free and reliable though? Not even close.
The Prairie 350 is a '01+, possibly an '03, I don't recall and I doubt I'll ever see it again as my ex's dad got rid of it AFAIK. The first CV axle falling out of the hub I wasn't present for, but I assure you it wasn't being treated roughly. The second one happened when I was personally riding the machine on flat level ground. Turning around, and clunk, the other one fell out when the wheels were turned all the way to lock. Quality. This being a couple of years ago on a low mileage newish machine. I wouldn't have touched one after the Bayou incidents, but this really confirmed my beliefs that they're garbage.
Now Hondas and Yamahas on the other hand, wow, I've seen plenty of them put through hell and come back, still run to tell about it. That includes a brand new Honda with even the handlebars underwater drug out, restarted and driven down the road. I don't have time here to talk about all I've seen them do actually. Antique 3 wheelers included, or maybe I should say, especially.
