1954 Chevy Truck Dashboard $45 - This would be a great piece to hang on the wall.
Chandelier $50 - I think this is pretty as is but if you wanted a more modern look you could always spray paint it.
Credenza/Buffet $75 - This piece just need a coat of paint.
Sideboard/Table $20 - I like the detailing on this piece, I think it would look really nice painted and in an entry way.
