Here's a couple of pics of my slingshot that I modeled after the old TV Batmobile. Its been updated even further with new seats and a quad tip rear exhaust that I painted red inside the tips just like the Barris Batmobile. I also switched the pinstriping from red to a red chrome that I found on ebay that matched the red chrome on the wheels real well. I'll update the pic after my next detail of the sling.
The double bubble windscreen would be more fitting but I don't think I would like the cyclone effect in the cockpit.
