Question regarding the order of adjectives, strictly for native American English speakers

I am a native American English speaker, although, I am interested in the following syntactic aspect, regarding the order of adjectives, as, here in the U.S. (Savannah, GA, to be exact), I’ve come across both versions – what’s the correct order of adjectives, in the following question: "a luxury 4-door sedan" or "a 4-door luxury sedan"? The one I’ve used all my life is: "a 4-door luxury sedan", although, I’ve heard quite a few people saying "a luxury 4-door sedan", in spite of the fact that the one I’ve used seems to be much more frequent, here in the U.S., statistically speaking, from what I’ve seen. I’m not exactly sure which one is syntactically correct and which of the 2 is the most commonly used phrase, that’s why I’m asking this question.
My question is strictly for native American English speakers, as myself. All help would be greatly appreciated.
Thank you anticipatedly,
The Unknown One
