Can the skill guarantee a part will fit or work?

No. It distinguishes verified fitment from conditional or unknown compatibility and flags condition or testing gaps. Confirm exact part identity and fitment with authoritative catalogs and have safety-critical items checked by a qualified professional before sale or installation.

Are listed prices the same as completed sales?

No. Active asking prices and completed-sale evidence are different. The skill labels them separately and, when authorized data is available, normalizes sold comparables by exact part, condition, fitment, date, location, shipping, and terms.

Does a positive profit calculation mean I should buy the part?

No. A scenario is only arithmetic from its assumptions, not a recommendation or profit guarantee. Verify identity, provenance, fitment, condition, sold demand, all costs, safety, and applicable rules before making a purchasing decision.

Auto Parts Resale Hunter — Research Demand & Profit

Example session with this skill installed

For a fictional donor sedan, I’m considering a used right tail lamp with an example-only label EXAMPLE-RH-LAMP-001. It is untested and has a cracked mounting tab. Purchase cost is $35; assume $10 inspection/cleaning, $20 packaging and shipping, $15 marketplace/payment cost, $10 returns reserve, and $15 labor. I have no completed-sale comparables or fitment data. Explain what must be verified, calculate illustrative break-even and profit at a hypothetical $120 sale (not a market quote), and flag risks.

Preliminary resale screen — fictional right tail lamp

Decision status: HOLD for verification. EXAMPLE-RH-LAMP-001 is a fictional placeholder, not a real catalog number. The donor vehicle, fitment, and condition have not been independently verified. No completed-sale comparables were provided, so the $120 sale price below is only a hypothetical scenario, not a market quote.

Identity and fitment checks

Confirm the number from a legible label or casting on the actual part; record brand, revision, side, market, connector, and any supersession.
Verify fitment against an authoritative OEM catalog or trusted interchange source for the exact donor vehicle, body, trim, region, and lighting configuration. Visual similarity alone does not prove compatibility.
Ask for photos of the lens, housing, connectors, all mounting points, and damage. A cracked tab can prevent secure installation or require a disclosed, compliant repair; do not represent the part as ready to install until assessed.
The part is untested. List it as untested unless a competent inspection establishes function. Check for water intrusion, broken connectors, internal damage, and missing hardware.

Illustrative economics (user-provided assumptions)

Item	Amount
Hypothetical sale price	$120
Purchase	−$35
Inspection and cleaning	−$10
Packaging and shipping	−$20
Marketplace/payment cost	−$15
Returns reserve	−$10
Labor	−$15
Illustrative net profit	$15

Break-even sale price under these assumptions is

$105 before taxes or other omitted costs. At $120, illustrative ROI on total cost ($105) is

14.3% and margin on sale price is

12.5%. These figures are arithmetic from the stated hypothetical inputs; confirm actual fees, shipping, tax, packaging, return exposure, and labor.

Market evidence still needed

Find completed sales for the exact verified part number and compatible variants, then normalize for tested/untested status, damage, completeness, geography, sale date, shipping, warranty, and returns. Keep active listings separate from sold evidence. If comparable sales do not support a price above break-even, pass or renegotiate.

Risk and next steps

Do not buy until real identity, fitment, lawful ownership/provenance, damage, and shipping economics are verified. Disclose the cracked mount and untested condition. Confirm applicable marketplace rules and local requirements; do not imply guaranteed fit or functionality. Recalculate with documented sold comparables and actual all-in costs before deciding.

About this skill

What this skill does

Auto Parts Resale Hunter helps lawful parts sellers assess identity, fitment, condition, demand, sold comparables, logistics, and resale economics before buying or listing inventory. It distinguishes verified information from hypotheses, active asking prices from completed sales, and direct fit from conditional or unknown compatibility.

How it works

The agent captures part and donor-vehicle identifiers, variants, side and position, condition, test status, source provenance, and relevant safety or regulatory flags. When authorized sources are available, it researches completed sales and normalizes comparables by exact part number, fitment, condition, location, date, shipping, and return terms. It calculates acquisition and preparation costs, seller net, profit, ROI, margin, break-even, and downside using explicit inputs. It can compare sales channels and part-out scenarios while listing assumptions.

Safety and legality

It does not invent fitment, functionality, demand, price, or profit. It routes airbags, seatbelts, brakes, steering, ADAS, emissions, immobilizer/security, high-voltage batteries, and hazardous parts to qualified verification and applicable handling rules. It does not provide unsafe repair, bypass, theft-enabling, or high-voltage instructions. Verify lawful ownership and provenance.

Limitations

Market prices and vehicle compatibility change and vary by region. Asking prices are not completed sales. A calculation is only as reliable as its inputs and comparable evidence; profit is never guaranteed. Confirm fitment with authoritative catalogs or qualified professionals before listing safety-critical items.
