- The three channels overlap less than 25% in buyer pools — running all three together produces more than the sum of the parts.
- Car-Part.com dominates B2B and pro-DIY parts buyers; integrates natively with Hollander, Pinnacle, and Checkmate.
- eBay Motors dominates retail and out-of-region buyers; shipping infrastructure unlocks national demand.
- Your own website earns the highest-margin transactions (no platform fees) and builds compounding local SEO equity.
- Fee burden ranks: eBay highest (insertion + 10–13% FVF), Car-Part.com middle, own site lowest at scale.
- Ramp time: Car-Part.com 7–14 days, eBay Motors 14–30 days, own website 4–6 months for organic compounding.
The question of where salvage yards should sell used parts online comes down to Car-Part.com vs eBay Motors vs your own website, and the honest answer for any yard above $500K in revenue is "all three." The three channels behave so differently — different audiences, different fee structures, different ramp times, different inventory logistics — that picking one means leaving 50–70% of available online parts revenue on the table. This guide compares them head-to-head so you can decide where to weight your effort first, then layer on the others.
This is the comparison view. For the operational guide to listing on each, see our how to sell more used auto parts online playbook.
Head-to-Head Comparison
| Factor | Car-Part.com | eBay Motors | Your Own Website |
|---|---|---|---|
| Primary audience | Mechanics, body shops, pro DIY | Retail, DIY, out-of-region buyers | Local SEO traffic, repeat customers |
| Geographic reach | Inter-yard freight + local pickup | National (parcel + freight) | Local + national if you ship |
| Fees | Subscription (varies by tier) | Insertion + 10–13% final value | None (hosting + SEO costs) |
| YMS integration | Hollander, Pinnacle, Checkmate native | Partial (third-party connectors) | Custom (depends on build) |
| Listing effort per part | Low (auto-published from YMS) | Medium-high (manual or assisted) | Medium (catalog or manual) |
| Ramp to first sale | 7–14 days | 14–30 days | 4–6 months organic, faster paid |
| Best for | Drivetrain, body, complete assemblies | Premium parts, rare items, retail-friendly | High-margin parts, repeat sales, brand |
| Buyer expectations | Hollander grading, condition reports | Photos, returns, fast shipping | Trust signals (reviews, ARA, BBB) |
Car-Part.com: The B2B Workhorse
Car-Part.com is the dominant marketplace for professional parts buyers. Mechanics, body shops, and dealership service departments default to Car-Part.com search before going to Google. The platform has been the industry's central inventory aggregator for decades, with integrations into virtually every major yard management system.
Where it wins: high-volume listings, drivetrain and body parts, B2B repeat buyers, native integration with Hollander Powerlink, Pinnacle Professional, and Checkmate. If your yard is on any of those YMS platforms, listing on Car-Part.com is largely automated — graded inventory flows in nightly without manual entry.
Where it falls short: retail buyers (DIYers searching for a single part) often start on Google or eBay, not Car-Part.com. The platform is also inter-yard-heavy — meaning many "buyers" are other yards sourcing parts they don't have, which has different margin dynamics than retail sales.
eBay Motors: The Retail and Out-of-Region Channel
eBay Motors expands the addressable buyer pool nationally. Where Car-Part.com is largely a regional B2B channel, eBay Motors lets a yard in southern Ontario sell a transmission to a buyer in Texas or California. Premium-margin parts — low-mileage engines, rare trim panels, OEM body parts for popular makes — often clear at 20–40% above local pricing on eBay because the broader buyer pool lifts the auction outcome.
Where it wins: retail sales, premium-margin parts, out-of-region demand for rare or in-demand items, parcel-shippable inventory, audience scale.
Where it falls short: fee structure. eBay charges insertion fees plus 10–13% final value fees on most parts categories, plus payment processing. The math tightens on lower-margin parts — a $40 trim piece loses $5–$8 to fees, which can be the difference between profitable and not. The platform also requires more manual effort per listing than Car-Part.com.
Your Own Website: The Margin Channel
Your own website is the highest-margin parts channel because there's no platform fee. A $400 part on your site keeps the full $400 (minus shipping); the same part on eBay loses $40–$60 to fees. The trade-off is traffic — own-website parts pages depend on local SEO to find buyers, and SEO compounding takes 4–6 months.
Where it wins: highest-margin transactions, customer relationship ownership (repeat sales without paying platform fees), brand equity, a destination for retargeting ads, control over presentation and trust signals.
Where it falls short: traffic acquisition. Without active SEO and PPC investment, the site's parts pages won't rank. The build cost is $3,500–$8,000+ for a parts-catalog-integrated site, plus monthly SEO investment to drive traffic. Best treated as a 12-month investment.
The "Run All Three" Strategy
The yards earning the most online parts revenue run all three channels simultaneously. The reason is buyer overlap is lower than yard owners expect:
- Pro buyers (mechanics, body shops) start on Car-Part.com — they may never visit eBay or your website.
- Retail buyers in your local market may search Google and find your website — they may never use Car-Part.com.
- Out-of-region retail buyers default to eBay Motors for shipping confidence — they're invisible to your local website and Car-Part.com.
The marginal cost of listing the same part on a second or third channel is low (especially with YMS integrations doing most of the work). The marginal revenue is meaningful because each channel reaches a different slice of demand.
How to Sequence the Three Channels
If you can't launch all three at once, the priority order:
- Car-Part.com first. Highest volume, lowest manual lift, fastest ramp, integrates with the YMS you already run.
- eBay Motors second. Multiplies addressable buyer pool, opens shipping revenue, complements the Car-Part.com audience.
- Own website third. Long-term margin play. Build it once Car-Part.com and eBay are producing predictable revenue.
This is the order most successful yards we've worked with followed organically.
Common Mistakes
- Listing on only one channel. Caps total online parts revenue at 30–50% of potential.
- Inconsistent grading across channels. Buyers comparing your Car-Part.com listing to your eBay listing notice the gap and lose trust.
- Same pricing across all three. Different audiences support different prices. eBay retail pricing should be 5–15% above Car-Part.com B2B pricing.
- No own-website strategy. Yards permanently dependent on platform fees instead of building owned distribution.
- Photographing only some parts. Listings without quality photos underperform regardless of platform.
Bottom line: Car-Part.com vs eBay Motors vs your own website isn't actually a versus — it's a layered strategy. Car-Part.com captures B2B volume with the lowest effort, eBay Motors captures retail and out-of-region demand at higher fees, and your own website captures the highest-margin transactions while building long-term SEO equity. Run all three; sequence them in that order if you have to start small.
Frequently Asked Questions
Should I sell parts on Car-Part.com or eBay Motors?
Both, plus your own website — the three channels overlap less than yards expect. Car-Part.com is dominantly B2B and pro-DIY (mechanics, body shops). eBay Motors is dominantly retail and out-of-region. Your own site captures local SEO traffic at the highest margin. Yards earning the most online parts revenue list on all three simultaneously.
What's cheaper — Car-Part.com or eBay Motors?
Car-Part.com is typically cheaper for most yards. Subscription pricing depends on volume, integration with Hollander/Pinnacle/Checkmate, and chosen tier. eBay Motors charges insertion fees plus 10–13% final value fees on most categories, which adds up faster on high-volume yards. Your own website has no platform fees but requires SEO investment to drive traffic.
Which channel produces the highest-volume buyers?
Car-Part.com produces the highest volume of professional buyers (mechanics, body shops, technicians) because that's where they search first. eBay Motors produces the highest volume of retail and out-of-region buyers because of its shipping infrastructure and broader audience. The buyer pools overlap less than 25%, which is why running all three together adds up to far more than running one alone.
Can I integrate Car-Part.com with my Hollander or Pinnacle inventory?
Yes — Car-Part.com integrates directly with Hollander Powerlink, Pinnacle Professional, and Checkmate yard management systems. The integration auto-publishes graded inventory from your YMS to Car-Part.com without manual re-entry. This is one of the structural reasons Car-Part.com dominates the B2B parts marketplace — the data flow is built into the tools yards already use.
Does eBay Motors integrate with yard management software?
Partially. Direct integration with Hollander or Pinnacle is less common than Car-Part.com's, though some yards use third-party connectors. Most eBay Motors-active yards manage listings through eBay's own seller tools, often with the help of an inventory uploader. Listing volume on eBay tends to be more curated than Car-Part.com because the manual lift per listing is higher.
Should I build my own website to sell parts?
Yes, even if you also list on Car-Part.com and eBay Motors. Your own website captures the highest-margin transactions (no platform fee), builds local SEO equity that compounds over time, owns the customer relationship for repeat sales, and provides a destination for retargeting ads. The build is $3,500–$8,000 for a parts-catalog-integrated site.
How do platform fees compare across the three channels?
Car-Part.com: subscription pricing varies by volume tier and integration. eBay Motors: insertion fees + 10–13% final value fees + payment processing. Own website: no platform fees, but ongoing hosting + SEO investment ($30–$200/month). The fee burden flips: eBay highest, Car-Part.com mid, own website lowest at scale but highest fixed-cost ramp.
How long does it take to start selling on each channel?
Car-Part.com: 7–14 days from sign-up to first inquiries if integrated with your YMS. eBay Motors: 14–30 days for first sales as the seller-score builds. Own website: 4–6 months for SEO to drive meaningful organic traffic, though paid traffic from Google Ads can produce sales day one. Plan ramp expectations accordingly.
