A 2009 Sigma three-seat tube chassis was a starting point for the Carwash buggy, which has been transformed from a pile of parts to an extreme machine capable of conquering the toughest trails. The YJ grille and hood give square-headlight guys something to root for, and the front and rear Rockwells with 54-inch TTC Claws make it nearly unstoppable. With three seats, there is room to carry a replacement spotter-just in case the original one can't hack it.A 2009 Sigma three-seat tube chassis was a starting point for the Carwash buggy, which has A.K.A. Carwash Mike "Carwash" Karwath of Union, Kentucky, has built quite a reputation over the past couple of years as he built up his 2009 Sigma chassis into a terrain-dominating implement of fun. This tube-chassis buggy polarizes the most hardened trail veteran with its mix of well thought out design, good looks, and quality fabrication. It is one helluva nice rig that any of us would be so lucky to have under our Christmas tree. Prepped for battle, the ultimate test of two years of hard labor was a week of hard fun.

Seems to be the biggest challenge of the week. Some seem to roll right through it and others have problems every part of the way. There also seems to be no rhyme nor reason to this success or lack of success. So I'm anxious to see how my team fares in the 'Trap." Not looking forward to: "The Mud Bog. Ugh. Mud sucks. 'Nuff said." Playing in his iPod/CD player: "Next four songs from the random playlist: 'I Go To Work' by Kool Moe Dee, 'Drink to the Dead' by Clutch, 'Gimme Back My Bullets' by Lynrd Skynrd, and 'Break 'Em Off Some' by Cypress Hill." Karwath says: "The big toenail on my left foot grows at a 45-degree angle, to the left." Functionality is the name of the game in the cockpit.
