I traded a 2010 GT 5 speed 3.73 gear base for a premium 2012 auto 5.0. Believe me, there is no comparison! The 2012 pulls MUCH harder. I drove a friends 2007 GT with a KB blower and a total of 14,000.00 in upgrades and my 2012 feels stronger. He has contacted KB numerous times to get it to run correctly. I feel something is definitly wrong with his car as I expected it to feel much quicker. Much happier with the 2012 as a bad left leg made the auto necessary. I am 64 years old and drove a ton of the 60's muscle cars. Stock none of them would beat the 5.0 and I am talking Hemi's, 440 six packs, 455 Buick GS, tri-power GTO's and 396 375HP Camaro!
