I'd say 24k would be about right for a black 08, maybe 26k at the extreme, the only one you can expect premium would be steel blue 08, the most rare of all. I still can't see the severe over pricing for the SRTs. That would be like me asking 20k for mine... I can ask it all day but at the end of the day, the value is only about 14k max.
I wouldn't ask for a penny less than $25,000 for mine. And that would be with putting it back to stock. Don't know if I would get that but I don't plan on selling it any time soon. That posting is definitely asking too much because usually the 08 SRT8's sell quick. That one has been for sale for 23 days.
