RE: Is the SRT8 worth 11K more than the R/T?
On what basis is it being suggested that modding an RT will end up costing more?
50 HP could easily be obtained for around 2.5-3K. Spending 10K-11K more for an SRT8 gets you get more standard options, but they're DODGE's options, not yours. If you want aftermarket wheels/tires, stripes, sound system upgrades, then you're really only getting 50 HP, in addition to suspension upgrades that are nice, but not necessary for a 50 HP upgrade. Brakes that are better, but not necessary for a 50 HP upgrade. I think anyone who is torn between the two models is looking through a "bang for your buck" scope. IMO the SRT8 doesn't supply this bang as much as the RT does.
Again, you could buy an RT, obtain 50 more HP through CAI, exhaust, chip and tuning, leave the suspension/brakes as they are, and still have around 7K left for other mods. How does that cost MORE than the SRT?
Lastly....if resale is a real factor, I would suggest the person buying is either stretching beyond their financial means, or that they have the luxury of financial indecision, the latter rendering their opinion fairly moot for the average person.
