I am a big Mopar fan and had an'69 Charger. I got a returned lease SXT with the 3.5 V6 for a great price and only 16K on the odo. I proceeded to upgrade it with a K&N CAI, magnaflow catback exhaust, dark tint, spoiler, custom 20" chromes, 6 Sony speakers and a nice faux wood dash kit. While I wish I had an R/T, the 3.5 is adequate and in all back looks baaaaaad! I am very happy and can haul the family anywhere in style. While my wife hates the loud new exhaust, she is now a fan of Mopar and will get a 300C after years of Ford ownership. Critics be damned, this is a fine car!
Looks, comfort and space, reliability and all the great after market upgrades, good highway MPG for such a heavy car (25-28mpg)
Fix blind spots, sportier dash, upgrade interior, drop the anemic 2.7, come out with a 2-door coup (Opps! that's the Challenger...never mind)
