-How long have you owned this and about how many miles did you put on it?
I purchased it in May 2020 at 139k miles.
-What is the oil consumption?
Ive not tracked it that closely that I could give you an exact number. I also don't drive that much. Id be comfortable saying it is less than 1qt/1000 miles.
-Do you have (and can you post) any pictures of the underside?
Ive uploaded more photos here: https://photos.app.goo.gl/bhELM2XSav2r3LrA7
-You mention maintenance records from previous owner(s). Anything worth noting aside from regular oil changes? I am thinking spark plugs & coils, cooling system, and/or AC.
Photos in the link above also have PO service records.
-Will it come with owners manual? How many keys do you have?
Yes, to owners manual. There is 1 key.
-Can you post a picture of the spare tire area? I am curious to see if the original tools are still in place.

-Can you post a picture of the tear in the rear seat arm rest?

-The "flaky" front passenger door switch, what impact does this have ... for example; does it prevent you from locking/unlocking the door.
The door locks and unlocks fine. The only problem this may cause is if you unlock the car, open the passenger door and do not open any other door. In this case, the system may relock because it thinks no door was opened. And the door puddle light doesnt turn on. None of these things ever seemed worth the effort of pulling off the door card to fix the switch.
-What aftermarket head unit does it have?
Pioneer AVH-2400NEX
