Orion Pax had created M.A.S.K stuff using lego he uploaded the pictures on flickr, 2 days ago, his boulder hill & rhino caught my attention.
In the 80s M.A.S.K was one of my favourite cartoon series, however the toys are quite expensive during that time. Back then, my brother's birthday present was Kenner M.A.S.K Raven, the only vehicle we had and we shared the toy. A few years ago, I bought M.A.S.K Switchblade with Miles Mayhem figure (the airplane/helicopter) on ebay.
Check his creation here (transfomers, he-man and other movies stuff), the Ghostbuster Car on page 14 is my favourite :
