The LEGO Batman Tumbler is one of the most iconic vehicles and the set has long been retired and costs a lot of money to buy from sites such as ebay.
However the good news is Tiler has reproduced The Tumbler in a black or camouflage version and created an instruction manual including a list of the 200 LEGO pieces you will need.
The building instructions set is available on Brickshelf and you can order all the pieces from BrickLink. Make sure you check the images in their original size for best view on details and building notes. The document is a pdf and 18m to download.
Thanks for the share Tiler!
