Hopefully the GTS becomes the next Ford GT. It is similar in a few ways, it has low production numbers, especially the 1 year only colors, it is an iconic body style that never goes out of style, descent performance and they are getting harder and harder to find nice low mile pristine cars. I cannot think of another car that made as big of an impression when it was released as the Viper. I can see the low mile perfect examples of these cars hovering in the 60's for a while. I know I wouldn't get rid of mine for any less but then I am biased and not motivated at all to sell mine.
It seems as if it is the Viper owners who are the ones that seem to want to undervalue them. I always found this as odd.
