I have a 2012 Chevy Silverado 2500hd with the lml duramax Diesel engine. This is a fantastic truck; looks amazing and runs even better! It's very classy thanks to the LTZ Z51 package giving it the tan leather interior, wood grain panels, factory navigation, heated/cooled seats, the works for everything this year came with. On the outside I've updated the mirrors to the newest model that have been color matched(also have stock power folding mirrors)all white leds all over the front. as far as modifications go it's pretty much stock for the exception of a straight pipe exhaust, deleted emmisions, a tune through ppei for mileage, and the cp4 has been converted to a cp3. other than that there's miscellaneous add ons. I'll say it again that this is a phenomenal truck inside and out! whomever becomes the next owner will not be disappointed one bit. DON'T LET THE MILES TURN YOU AWAY. IT'S ONLY 4 YEARS OLD AND THESE MILES ARE NOTHING ON A DIESEL ESPECIALLY A DURAMAX. there are older model versions of these trucks bringing this much or more If you have any questions or would like to see it please feel free to call or text me @ 85968476onezero thanks.
