Whats a 70 BB Charger and Road Runner worth?

Lets just say that I havent seen anything as "nice" as these cars for lass than $10K in the last few years. I am thinking he would probably take $2500-$3000 each and maybe less for all. Paid $1500 for super clean 67 GT w disks console etc. It has 0 rust and is super straight. Looks like it might be time to add another one to the resto list. I did look on B bodies a bit but will give it a closer look today.
