One of the unique features of the Doon not found on any other UK buggy kit is the finished return lip around the whole perimeter of the main bodyshell tub. This not only adds immense strength without any additional weight but helps stiffen up the whole of the kit, removing the body shake traditionally associated with beach buggy kits. But perhaps most importantly, the return edge provides a neat and finished look to the outer edge of the kit ensuring no raw, rough cut fibreglass edges are seen.
