Does anyone know how Signature Models are? They look pretty nice (not astoundingly detailed but good) for the price point. They have an insane number of features (windows that roll up and down? Yes please!) but no site I’ve read says anything on how well built they are. I have seen a few complaints about plastic-y seats and undetailed engines, but if those are the only problems, then I’ll be getting 1 or 2 or 5.
