This truck had no flashing, lines are crisp, and should not have any problems, Except One = I bought this for my 33 year old daughter she can not decide whether to build as Smokey and the Bandit 2 or as Coca cola truck ? I say we'll buy another. Instructions are pretty cut and dry easy to follow since we been playing with model for years. As for Cons= haven't got any as we haven't started on it yet.
