70 AAR Cuda ...what's it worth?

[SS4Real]

Need some guidance from you MOPAR fans. I've got an older friend in town who has a 1970 AAR Cuda that he is thinking of selling...but not yet. He would like to get an idea of it's value versus selling one of his hot rods as he has too many cars in the garage. The car is numbers matching (original engine, transmission and rear end)with the build sheet. Car is Sassy Green (lime green), no vinyl top, black interior, automatic with headers and minor changes from stock such as hotter cam, headers, etc. This Cuda is a #3 condition car with about 75,000 miles on it. What's a ballpark figure of it's value?
