Suppose I were to say this sentence: "I own a 2003 Ford F-150."
Would 2003 Ford F-150 be a compound proper noun?
Would Ford F-150 be a compound proper noun and 2003 be an adjective?
Would F-150 be a proper noun and 2003 and Ford be adjectives?
Am I way off, and there is some other term for this?
It's been a while since I've taken any sort of grammar course, so I'm admittedly rusty on some specific instances like this. I honestly don't think #3 is the correct answer, as Ford seems like it would definitely be part of the proper noun, but I included it just to be thorough.
