Having been around the bearhawk community a bit, knowing what I know about them, I would say buying a used bearhawk is just like buying any other used airplane, there are significant pros/cons.
Bearhawk pros:
If you don't like it, change it. If you want a longer flap handle, build one and install it. If you want a different battery, swap it. If you want to run 39" hand molded tires, gopher it. Well, except since you didn't build it, you would have to find an A&P that would agree to doing such stuff and signing off on it.
It's a good flying airplane. The airfoil is very similar to a Sedan, it works well.
The cabin is much roomier than any Maule I've been in, but I haven't been in a newer one.
You get nice glass cockpit.
It's new. There isn't any hidden corrosion, or decade old repairs that weren't done right.
That one has balanced injectors and can run lean of peak for very good fuel economy.
Sporty handling.
Bearhawk cons:
Parts aren't mass produced, and therefore are fitted. You might find stuff like one one part slightly longer than another, or the door from another bearhawk doesn't fit on this one. (But, you could just make another part from the plans, and fit it to your airplane.)
The gear is aligned by heating it up and bending it, which is the same as most fabric airplanes, but needs to be right otherwise they are a handful. Also, the shocks aren't that strong, so you can't be an idiot landing it, like any tailwheel.
They don't have fowler flaps, just barn-door flaps that pivot straight down.
They aren't quite as clean as a 180, and therefore can be slower. The tail has flying wires, lift struts, and trim push-rods all out in the wind. Add in the gear, and it's just not as clean as a spring gear Cessna that has none of that stuff on the tail.
I don't like how that one has the fuel lines up to the dash for the fuel selector valve. Lots of fittings/weight/and a high point in the fuel system.
Cost. A nice bearhawk is going to be expensive, a not-so-nice bearhawk, isn't something you want.
It's experimental. So we don't know exactly how they fail. 50 year old certified airplanes have well documented and understood failure modes. Bearhawks can be pretty one off. That one might have a fuel system mode of failure that none of the others have due to where the fuel value is mounted. What might be a problem on one may not be a problem on another, though the kit minimizes this to some degree.
Personally, for that much money, and if I couldn't be the repairman, I would be looking at a super cherry Cessna 180. They don't make them anymore, and if you have a good one, it should hold it's value for a while. Bolting up floats/skis is more expensive, but trivial as the engineering is done and sound.
All of that said, I am working on my bearhawk.... I am convinced I can fix the things I don't like (mostly) and that having a NEW airplane, with an AMAZING panel, that I can maintain myself is worth it to me.
