hey ATV/qaud guys...need some advice

I highly recommend to stay away from Polaris and Yamaha and anything two-stroke.
The Polaris will kill you with REPAIRS and maintenance, especially wiring. They are cheap to buy used or new, for a reason, and need suspension help if you hang a plow or a winch on them. But they ride pretty nice,lol.
The CVT is a high maintenance item as well.And they eat tires, and steer like crap.
The Yammys are not quite as bad, but are built like dynosaurs. Maintenance will be a bit cheaper, and they don't break as much parts. I call their assembly stack-technology. Everything is stacked one thing on top of the next and the parts most likely to fail are at the bottom of the stack. At $100/ hr, a lot of time is spent simply unstacking and restacking, driving repair costs quite high.
I worked at three dealers over about 25 years or a bit more.Polaris, Yamaha, and Honda; so I didn't see many Kaws. (BTW: I like most Kawasaki's), consequently
I can't speak to Kawasakis.
Hondas were, during all those years, the most robust and with no belt-driven CVTs, the cheapest to maintain and had low repair costs. Their suspensions were up to the task, and the engines were practically bullet-proof.

My opinion is this; if you buy a Honda, the buy-in is a lil higher, but after two years or less you will likely break even, and have had no down-time. So in the end, they are cheaper.
Withoutexception, everyone who ever asked me , and didn't buy the Honda, regretted it.
And as stated above, the Foreman 350 is a sweetheart of a machine, adaptable to almost anything... except of course maybe racing,lol.
They will also pull a lot of weight along the ground, or on the racks, and are nimble enough for an adult to have fun with. Yet docile enough for a young experienced rider that can comfortably reach all the controls. There is only one downside; if you manage to get it stuck, you'll need either; a winch,a pick-up truck, or several tough guys, to retrieve it,lol. So if your kid comes home and says he's stuck, he really will be stuck. Go out prepared for the worst,lol.
Also with the Foreman, you can do almost all repairs to the engine or trans short of a crank,with the engine in-frame. Not so with some other brands. Also, IIRC, the 350 is a pushrod, sideways-mounted engine, so if you manage to cook a piston, the barrel comes off in a few minutes. Clutch work is a lil more difficult, but the entire rear end unbolts in a few minutes, and then you have plenty of room.The steering is tough, and with a bit of fine tuning is stable and comfortable at speed. The diffs are almost indestructible.
