Girls, do you believe in the perfect package in a boy?

If a guy(take me for example) has a beautiful personality, an okay face, is very polite, well-mannered and nice, treats you like a princess and has a chiseled body all around, do you tend to think that he's too good to be true? Like, if he asks you out, would you say no out of doubt,his looks, or thinking he's too good to be real?
