It's a very cool truck and a fun build. Simple, but cool design. It uses 4 side exhaust pipes that aim upward for a more dynamic look. We used the roof from the Lego Monster Fighters Dracula's Hearse. This amazing build is perfect for the person who loves monsters and hot rods. It will fit a minifigure in the driver's seat as well as 2 more in the truck bed. The two front wheels are narrow and smaller than the wide back wheels like most dragsters have. It even has decorative chains along the roof.
