"...you can buy ... a piston from a car actually driven in a Formula One race costs $1,025, to be used as a paperweight or desk ornament. A chromed camshaft, ideal as a sculpture, sells for $5,165; a 10-cylinder engine block, also a sculpture, for $70,800."
Uuuuuuuuuh, ya, "you CAN"...but why the devil would anyone actually do so? :shrug
