Specifically, I was looking at (both roadsters) a 6spd for $12K with 70K miles and an SRT-6 for $18+ with 70K miles. Was wondering if the SRT6 was really worth an extra $6K. I see the SRT6 sold, not sure at what price, so I know there is more desire for that car, but not sure I can make myself believe it can really be $6K worth of difference. Would think I could do quite a few upgrades to a limited for $6K... Thoughts?
