I have two 1999 Max 6-wheel drive amphibious vehicles for sale. One is a Max II (2 seater) and the other is a Max IV (4 seater).
Check my Craigslist ad for pics...
The Max II has a heated throttle cable and the larger wheels. The Max IV has heated throttle cable, 2 sets of wheels, full tracks, winch, plow, roll cage and rear cargo rack with gun holders.
Both are in good shape and need nothing mechanically. They're made by Recreative Industries right in Buffalo.
I'm selling these tio try and make room for an 8 wheel Argo with tracks that I've decided to buy. I'll try and get some pictures up later. Both can be seen and test driven at my marina on Canandaigua Lake.
I'd like to get $2200 for the Max II and $5000 for the Max IV. PM me for more details or my phone number if you want to discuss either.
