so, you honestly think that the challenger with a 6.4L, 525hp engine is going to cost less than the 425hp 300C srt8 with the 6.1? keeping in mind that the viper, with only 505hp, was over $80,000...im not saying that if we see a 6.4L powered challenger its going to cost 80 grand, but i cant forsee them asking less than the 40,000 price of the srt8 300c...the shelby gt500 has an msrp of 42,000-ish...and they are on lots now, so with a little effort, you should be able to find one without a huge markup, but the same way that the C6 vettes and the gt500s were marked up, you can guarantee that the same will happen with any challenger, especially one with a 6.4. also keep in mind that if you were to buy a base model challenger, say that its 30,000...not including any labor costs, the 392 hemi crate motor is around 16,000 dollars. that doesnt include the built transmission or dana rear diff in the SS concept...
