Looking at an E body 70 challenger

I kick myself at least twice a day for selling my barracuda. It wasn't perfect by any stretch it needed alot of body work and interior work but it did run and drive. And I sold it for $3500 back in 2009. Now they are 20k for one like I posted above. Makes me sick. I always had the intention of buying another but I know that will probably never happen now.
