Hey guys, I'm debating over a 2005 and a 2006 cts. The 06 is a little more expensive, but I like the simi-automatic transmission. The ability to shift gears manually really catches my attention, but I want to kno if its worth the extra money. They're both 3.6's, so I know there's no horsepower difference, but I just want some opinions from people that have driven both. Please help, all opinions are helpful to me. Thanks.
