What a buyer is actually judging

A private buyer walks up to a car and forms an impression in the first minute, and it is built from three things in roughly this order: the smell when the door opens, the condition of the driver's seat, and the paint in whatever light is available.

None of those is about the mechanicals. All of them are about what the buyer believes about how the car was treated. A clean-smelling car with a decent driver's seat and paint that reflects properly reads as maintained, and a buyer who believes a car was maintained does not negotiate as hard. That is the entire value proposition, and it is worth a great deal more than the cost of the detail.

The order to do things in

Detail first, then photograph, then list. Every version of doing it in a different order costs money.

Photographing a dirty car and detailing it later means the listing photos undersell it and the buyers who click through are already discounting. Detailing it two weeks before listing means it has collected dust and a fortnight of use by the time anyone sees it. The right sequence is a full detail a day or two before the photographs, photographs the same day, listing the day after.

What is worth doing and what is not

Worth it: odor, always — a car that smells of dog or smoke is discounted before the buyer sits down. Interior surfaces and the driver's quarter. Paint decontamination and protection, so it reflects in the buyer's driveway. Interior glass, which affects how the whole cabin reads.

Sometimes worth it: light paint correction on a higher-value car where the swirls are obvious in sun. The return on correction is real on a car worth enough that condition moves the price by hundreds rather than tens.

Not worth it: fixing things that are honestly worn. A twelve-year-old car with a worn driver's bolster is a twelve-year-old car. Buyers expect it. Trying to hide it reads as hiding something.

Trade-in versus private

A dealer appraiser is judging faster and against a different standard: reconditioning cost. A car that arrives detailed is a car they do not have to recondition, and that shows up in the number. It is a smaller effect than in a private sale, but it is still worth more than the detail costs on most vehicles.

If you are choosing between the two, a detailed car does better in both, and the private sale is where it does best.
