Junkyard auto parts eBay store in Detroit: an idea check

We checked an eBay store selling used parts pulled at Detroit-area junkyards to buyers across the US. It scored 59 of 100, "Possible, with caveats"ch. Interest in DIY repair and used parts is rising, but junkyard chains and online sellers already serve the market, and parts quality is the main trust issue.

Idea

eBay store reselling used auto parts pulled at self-service junkyards around Detroit, run from a home garage: DIY mechanics and car flippers nationwide

Problem: Finding cheap, genuine used OEM car parts without paying junkyard or dealer prices · Offer: Used auto parts pulled at self-service junkyards and sold on eBay

59of 100
The first check of the ideaPossible, with caveats

The idea has real demand signals and a clear price edge, but there is no search-volume data, the closest competitor already covers about 55% of it, and unit economics are an unmeasured category estimate, so it is possible but needs proof before building.

No data, left out of the score: demand, unit economics

Strong price edge

Used parts sell 20% to 80% below comparable new parts, so buyers have a real reason to choose used. This is the core pull of the idea.20

Quality is unanswered

Three complaints about quality exist and no competitor compete on them. A tested-and-warrantied offer could own this gap.145

Incumbent covers most

Pick Your Part already offers about 55% of the idea, so range alone will not win buyers.

Demand is unmeasured

There is no search-volume data for this market, so demand cannot be confirmed yet.

Closed rivals warn

Carsabi lost its traffic when Craigslist blocked access, and Vroom shut its e-commerce operations, so channel dependence is a real risk.910

Trust is fragile

Buyers complained about reliability and one described a seller that never existed, so trust must be earned early.621

Two free channels

eBay search and the Google query on cheap used car parts have no direct competitor in their top 3, so organic entry is open.

Margins are unmeasured

Unit economics are a category estimate, not measured in this market, so the margin case is unproven.

What the idea covers

  • ›Quality — Tested and photographed parts may reassure buyers, but no quality guarantee is described.
  • ›Price — Pulled parts at yard prices undercut new parts and dealer prices.
  • ›Reliability and trust — Used parts carry risk; a warranty would be needed and is not described.
  • ›Service and support — The idea does not describe customer support or returns.

No data — not in the total—

The price's basis: Reported junkyard prices start around $82 for a brake caliper; frequency of purchases per month is an assumption, not in the data.

The estimate does not hold: on the category's norms LTV/CAC comes out above 20 or a customer pays back in under half a month, which no real business shows — the prices found or the purchase frequency do not fit this idea. Count it on your own numbers: the price, the purchases a month, the margin and the cost of a customer.

Questions about this idea

What do the customer economics look like?

A general e-commerce model estimates a $82 ticket, 3 purchases a month, a 25 % margin, a $492 LTV, and a $25 CACch. These figures come from category norms, not measurements in this market.

Who am I competing with?

Self-service yards such as Pick Your Part and Pull-A-Part, online used-parts sellers such as Premium Used Auto Parts, and an existing eBay store, American Auto Parts. Pick Your Part already covers most of this offer, so some buyers may stay with it.

What risks should I plan for?

Buyers complain about bad parts and refused refunds, and one poor part could damage trust in a new store. Parts prices can also swing and squeeze margins on stock you bought high, and you will need a business licence and to follow selling rules.
