Just my opinion....
The vast majority of the SRT-10's will be worth very little due to mods, wear and tear, rust, accidents, unwanted paint, interior mods, kinda like most classics.
The worth will always be presumed to be worth more than it's worth or equal to something that just sold on Barrett Jackson and most of us know that not every truck will get that big sale price.
The ones I think will be the greatest value:
The two all white CE's, providing they were documented well by Dodge
The two VCA's with the Auto's, (best info to date crushed, therefore unobtainable)
#400 Night Runner, last one sold and has the sigs of all the people that worked on the line
#0129 or 3057, GUINNESS BOOK OF WORLD RECORD SRT-10
#007 Yellow Fever, used in print ads and has a marketing history
From there, I think the most desirable to own will be in the following order:
CE's
VCA's
2006 Flame Red
2006 Bright Silver Metalic
Night Runners
Any 2004
Yellow Fevers
2006 Brilliant Black Crystal
From there, my opinion would be there all pretty much the same. The production totals, although I think they may make a difference, my guess is the $$$$ difference will be very little.
but then again, what the hell do I know
