diesirae,
Welcome to the forum. I really like your picture. If your willing to spend some cash on the garage I would put up dry wall and paint it as Peter suggested. You could also tile the floor with Linoleum which is durable and easy to clean but Peter is right the list goes on and on.

You have some very beautiful cars. Do you have a favorite among the two? I really like the color of your Testarossa. I've seen that color in person on F355s but never a Testarossa.
