This is how to use AI to tell if something is overpriced

This is how to use AI to tell if something is overpriced.

Last month a mechanic quoted me $1,140 to replace a starter. It sounded high. It also sounded like the kind of thing where, if I pushed back, he’d say “parts have gone up” and I’d have no idea whether that was true.

This used to be the moment where you either paid up or spent your evening in forums reading posts from 2019. Now it takes two minutes.

The move

The trick is not asking “is $1,140 too much for a starter?” That gets you a vague range and a shrug. The trick is giving the AI everything a knowledgeable friend would ask you first:

• What exactly is being sold or quoted (the itemized version, if you have it)
• Where you are, since labor and prices vary wildly by region
• The specifics: year, model, condition, brand, mileage, whatever applies
• What the seller said to justify the price

Then ask it to break the price apart instead of judging it whole.

Copy this prompt:

I was quoted $1,140 to replace the starter on a 2016 Honda CR-V in [city]. The quote breaks down as $520 for the part and $620 for labor (2.5 hours).

Break this down for me:
1. Is the parts price in a normal range for OEM vs aftermarket?
2. Is 2.5 hours a reasonable labor time for this specific job?
3. Is the shop hourly rate typical for my area?
4. What questions should I ask before agreeing?
5. If it is high, give me one polite sentence to push back with.

What came back

The part price was fine. The labor time was the tell: this job is commonly booked at 1.2 to 1.7 hours, and the AI told me exactly how to ask about it: “Can you walk me through why this is booked at 2.5 hours?” The shop revised the quote to $890 on the spot. Nobody argued. The number just had to be looked at out loud.

The same structure works on almost anything: a couch (“is this fabric grade worth the markup?”), a “40% off” laptop (ask what the model actually sold for last quarter), a wedding photographer, a plumber, a used bike.

Where to be careful

• AI prices can be months stale. Treat its numbers as a sanity range, not gospel; the reasoning about what drives the price is the reliable part.
• It can’t see condition. For used things, photos help a lot. Share them and ask what to inspect in person.
• One quote is still one quote. The AI’s best trick is telling you whether a second opinion is worth the hassle.

This is the kind of thing that quietly pays for itself a few times a year, and it makes you the person friends text screenshots of quotes to.

This is how to use AI.
