Has got to be this, its ugly as hell in my opinion.
To give you a bit of background info on these "Artworks" ( I use the term very loosely) , they are called Dekotora or Decotora trucks, they are a hit in Japan and go hand in hand with Boszoko cars and Vans even bikes if you can believe it.
All in the name of having the most standout car/truck/bike. They are actually using those trucks day to day for their business, but are not allowed to turn the lights on while travelling on normal highways. And the reason I quoted the post was that I think there is not one truck in this world more hideous than those things imho.
