The duPont Registry is home to so many toys that I will never afford, this $225,000 Jeep Wrangler pictured above is no exception. It’s an absolutely incredible machine and build. I’d love to buy it and take it to this year’s King of the Hammers, it would probably have a decent chance of winning. The list of custom parts, performance upgrades, etc… is unbelievable, you can check it out below.

The heavily modified Jeep Wrangler, dubbed Project Rattletrap, is a ground-up custom job that took Martin Barkey Racing Products a year and a half to put together. The part list is incredible but the real star is the engine, a twin-turbo 5.9-liter 12-valve Cummins diesel that puts out 500+ Horsepower with 1,000+ plus lb-ft of torque.

Here are a few great videos of the Rattletrap:
