it pains me to say it because i really want to see the end result, but i would say sell it now and not finish it. if you finish you will probably take a bigger hit and a bigger risk finding someone that loves it enough to pay. if you sell now someone will have a good start to a unique custom 3rd gen and they can tweek it how they want.

personally it wouldn't have taken me so long to decide on a charger over a 3rd gen camaro
