I answer this question this way. It would cost you WAY more than $10k to turn an R/T into an SRT8 so consider all the extras a bargain. You sound like a guy who likes to mod his rides. Me too and I have finally learned my leasson. I've tried to turn a '67 GTA into a Shelby and then a Super Snake and spent WAY TOO MUCH MONEY. Could have just bought an original Shelby GT500. If I had just bought a 911 C4 I would have saved money over buying the C2 and modding it. Don't get me started about the '02 RAM Sport that desprately wants to become an SRT10 Ram. The list of mods on that thing will make you cry. Go for the SRT8, my friend... unless you think the wife will leave you when you start to drive HER Challenger too much...
