Got bit by the Buick bug after seeing this 1950 Buick Roadster convertible

Hi all just signed up for the $2.00 option :) Saw this Buick and just fell in love. I want to try to find one with a nice patina on it and leave the exterior as is but then update the underbelly with a nice reliable engine, trans, IFS, REAR, Bagged, Etc. If anyone knows of a 49-53 Buick Convertible for sale let me know :D Also if anyone has built a 49-53 if you have a build thread I would love to see! Or any advice on a build.
