Not as extreme as the Japanese vans but....an Ice Cream Truck? http://cgi.ebay.com/ebaymotors/ws/eB...&category=6173
And i just found this too so i'm gonna add it in. These people want you to pay 1,000,000 to ONLY buy their plans for this personal submarine.
It says: "This are the complete designs for a prototype of a new submarine. The package includes technical assistance and engineer to help build the sub (buyer will pay the salaries, transportation and living cost) plus the cost to build the sub." http://cgi.ebay.com/ebaymotors/ws/eB...category=26434
Sorry but ugh for that much that **** better be built for me already. And those are the cheapest pictures of a sub i have ever seen. Somone spent....20 minutes in MS Paint making those. lol
