KR> Question about airworthy certificate

[randy white]

My KR2 was flyable when i bought it!!! but i took it all apart and did some 
repairs and had the engine rebuilt changed the retracts to fixed !! 
basically built a new plane!!! im going to sell it when its all done,my 
question is, should i sell it as a new plane and let the new owner get a 
airworthy certifcate or should i keep the one i have and just get a annual 
passed on it!!!what would be better for a resale? Thanx Randy
