I have one brand-new (never used/installed) red Schroth Profi III-6 point harness for sale.
The harness has the pull up and snap-in style lap belt, and comes in the original box.
I purchased it new from HMS, but after deciding on a different harness for the passenger, I missed the return window.
It currently sells for ~$340 + shipping online, so am asking $315 + your choice of shipping.
