BartZ28

Black on black. Everything is stock. 50k miles. Immaculate and I mean immaculate condition. The ash tray lid is the only defect. Garaged since birth. Service records since birth, available. Value?

Are you selling or buying? We could use a few more details, like if the tranny is auto or stick, any options, etc....
In the meantime, (either buying or selling you can use these parameters) if the title is clear with no Carfax issues, and the car doesn't need expensive items (like tires) then an 'excellent condition' one owner Z28 could command $12,000. Stock, non abused, one owner F-bodies are always very desirable and at the top of most buyers lists, especially with full maintenance records. You seem to have it all if the car is as immaculate as you claim. If no bites at $12,000 after a few weeks, lower to $11,500. I wouldn't take less than $11,000, well maybe $10,500 if a buyer was in your driveway with $100 bills in hand. GLWS!!
Just remember to be patient if selling. These cars are not 'flying off the shelves' but if priced right, and described accurately, you will have no problem.
