I love this game...guess the value of the car...one of my favorite. Given the 2 pictures and provided information I will say $4K (plus or minus $2K). Need engine pics and interior pics to offer a better estimate and reduce the tolerance. Hard to tell if the paint has been oxidized, what do frame rails and floor pan look like, how bad is rust under battery. How original is the engine. Original spare? My '73 still has the original exhaust system and it has 147K miles. Throw on the webbers or round tops and you reduce the value of the car. Reduce by $1K for the webbers, Reduce by $500 for the round tops. Only because the car seems very original. The more you change, the less it would interest me. ( Just my opinion-I am sure there are others that feel different) If you can salvage the paint, maybe add $1K to $2K for that. How's the chrome? '73 probably not the most desirable year: 70, 71, 72 would be better. All in all, VERY NICE CAR. I love the color. Congrats on the find. Rich
