From a distance perhaps. Up close the build quality isn't great. And riding in them for more than a few minutes is rather unpleasant, at least compared to a decent car like a Honda Civic or something. The cheapest cars really skimp on noise insulation, seat supports, and suspension damping to hit those price points.

I agree on most point but why would more damping could increase costs? Apart from the fact that one can increase ground clearance and soften the spring, thus resulting in stronger damping, the cheap gas monotube suspension price isn't really sensitive on the damping force required for normal applications
