I would clean the Buick up a little bit and sell it. Its a beautiful car and a great (almost finished) project for someone. It will sell. You may not make all of your money back but you'll get a good price for it. If you paint it; youre only going to loose more money (couple grand in paint and paint supplies to prep it). That Model A is absolutely gorgeous and inmy personal opinion; wouldn't touch it. Its an heirloom now and that is one beautiful car. Have you thought about putting a hot rod engine in it? That way it would be fun to drive but with the hood on it will still look stock. You could take the hood off for a more traditional hot rod look. Not all Model A hot rods should be chopped and I think a lot of them are just overdone. Why follow the crowd? I would sell the buick; take the profit and tuck it away and start saving your pennies to add to that profit. You will save up enough to purchase a model A worth hot rodding. don't worry about that . Good luck!
