Whats a 70 BB Charger and Road Runner worth?

you can find a 69 roadrunner, all there for $5000, ya got to look. 68-70 bb chargers are more, and cost more to restore if all that welded together rear sheet meal has to be replaced. and grills are high..
if you want appraisals, you need to send some good vin/fender tag info and pics for our guesses.

yes, look on FBBO, also check and what actually sold and contact seller and see what he got, IF he will tell. our economy in general is still soft, and the old mopar market still feels its effects, IMO
buying a good desirable project worth its price is always a challenge.
