I have a sharp 1997 black on black convertible roush with 60,000 miles that I need to sell. What shouldI list this for?

Always a tough call but, finding what a 97 vert is selling for in a similiar condition then add the depreciated value of the package you have is the fairest way.
Ballpark ... not certain as to what qualifies as 'sharp' ... $10K. Hope that helps as a starting point.

Where is the car located? Got a pic or more info?

Pics please!!!
