Hello, all,

What would be a value of a numbers matching '69 Nova SS L78 4-Speed Car?
The car has all numbers matching. The original engine is was gone through about five years ago, 0.030 over with TRW replacement 11.0:1 pistons, Crane blueprint-series cam matching the original specs and new matching Crane solid lifters, new GM rocker arms, balls, pushrods, rebuilt original water pump, original alternator, rebuilt original carb., new high volume oil pump, balanced and blueprinted, reconditioned original crank and rods. Engine has not been fired. All of the original parts were retained where possible, including exhaust manifolds. A NIB performance clutch & pressure plate are with the car. Front subframe is out, and rebuilt with Polygraphite bushings and other components. Body is original frost green color, with black interior and black vinyl top. One door (passenger side) appears to have been replaced at one time. All other sheetmetal is original. Original black bench front seat. Rubber floor mats. Original M21 four speed and 3.55:1 posi. Vintage Sun tach mounted on steering column. Power front disc brakes. AM Radio (not working). Body has nothing but light surface rust here and there. Body is straight other than basic nicks and dings. Has original radiator. Car has 65K original miles. Original shifter. Front end of car is off. Car has been stored indoors in heated garage for 9 years. All parts are there. There are a couple of original copies of the build sheet found in the car. This is a solid, original, numbers matching car that was taken apart for a restoration, and the owner just didn't have the time/money to finish the project.
The question is...in this condition, what is a reasonable retail asking price for this car?
