The ones u should of kept

I was thinking today about some of the cars I should of kept and never sold...here one I was almost done with and decided to sell it a couple yrs ago...I sold it to a very nice gentleman who finished it up and resold it again....the car was a very nice car that I should of finished up and took it to car shows with my son..so now we're trying to get our roadrunner finished up to take it...but thought I'd like to see and here some stories about that special car u let go of
