First -- I'm a guy that owns a black truck - a black trailer - a black MBZ and a black Porsche....
LEAVE THE BLUE ON IT! It's killer!
I love the blue and the paint and body appear to be great....
I'd ditch the super skinny sidewall tires.... put a bit more "wubba" under there... and do a trick chassis (Ironworks is building a new one that looks great)... and do any other little fix ups that you want to do.
Just my .000000000000002 worth.
