Nope, They did that blue on the replica cars for '98, which still didn't look at all like the actual pace cars... In '99 they were only produced as actual pace cars. That car is worth quite a bit more than any replica car produced. We are talking like 3, maybe 5 ever made, rather than well over a thousand... For only having 20k miles on it, I would put it in the ballpark of 20k, especially if ALL of the documentation is present. An auto museum would LOVE one of these... lol just a thought.
Or you can try to hold onto it, it's really clean from the looks of it and selling locally might not net you what the car is actually worth. Anyone that will pay 20k for it, you know will take care of it.
