$300. NMNA. I can put eyes on it if you'd like.

That thing is super cool. $300 seems like a steal. Fix the motor, add a set of turf tires and a box on the rear, and you have a super cool yard cart.
Fix it? My buddy's got 23 motorcycles and a garage full of parts, pretty sure there's an air cooled something with more ass than a Cushman.
I think they even used lawnmower engines too, like a flat boxer Onan.
Damn, I'd buy it in a second if I wasn't half the nation away.
Sitting in the center, just jump out the high side. The one for $300 has tubing at the front corners, be easy enough to add two castering wheels for the faint hearted.

Don't use the Top Gear Reliant episode as basis, because to do that they had to weld the diff and load the passenger side with concrete to get it to flip- you can see that because it always flipped on the passenger side.
But for these? Terrible! They can totally flip per old users of them lol, their wheelbase is too short and tires too small. To get a 3-wheeler with a one front/two rear setup to not be imbalanced requires a long track width and rotation to angle the front wheel into turns, otherwise the opposing rear wheel pops up. It's why most three-wheelers go delta, or two front one rear configuration.
Basic info about 3-wheel vehicle dynamics
Like a four wheel vehicle, a three-wheeler's margin of safety against rollover is determined by its L/H ratio, or the half-tread (L) in relation to the cg height (H). Unlike a four-wheeler, however, a three-wheeler's half-tread is determined by the relationship between the actual tread (distance between the side-by-side wheels) and the longitudinal location of the cg, which translates into an "effective" half-tread. The effective half-tread can be increased by placing the side-by-side wheels farther apart, by locating the cg closer to the side-by-side wheels, and to a lesser degree by increasing the wheelbase. Rollover resistance increases when the effective half-tread is increased and when the cg lowered, both of which increase the L/H ratio.
A simple way to model a three-wheeler's margin of safety against rollover is to construct a base cone using the cg height, its location along the wheelbase, and the effective half-tread of the vehicle. Maximum lateral g-loads are determined by the tire's friction coefficient. Projecting the maximum turn-force resultant toward the ground forms the base of the cone. A one-g load acting across the vehicle's cg, for example, would result in a 45 degree projection toward the ground plane. If the base of the cone falls outside the effective half-tread, the vehicle will overturn before it skids. If it falls inside the effective half-tread, the vehicle will skid before it overturns..... The single front wheel layout naturally oversteers and the single rear wheel layout naturally understeers.
