What is WebAutoCats.com?
WebAutoCats.com is a web resource that gathers original parts catalogs for a range of car brands in one place. It is aimed at people who need to look up genuine (OEM) part numbers and catalog information rather than buy parts directly. The site covers several manufacturer catalog systems, including ETK, ETKA, PET, and EPC, spanning European and American brands.
What the site provides
The core offering is access to original parts catalog systems, each tied to specific manufacturers:
| Catalog system | Brands covered |
|---|---|
| ETK | BMW, Mini, Rolls-Royce |
| ETKA | Audi, Seat, Skoda, Volkswagen |
| PET | Porsche |
| EPC | Mercedes, Smart, Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac, Saab, Saturn |
These are the same catalog families dealerships and workshops use to identify factory parts. The site positions itself as a discovery, directory, or archive-style resource, meaning it points you toward these catalogs rather than acting as a storefront.
Who it is useful for
- DIY owners and enthusiasts who want to confirm a part number before ordering from a dealer or aftermarket seller.
- Independent mechanics who need to cross-reference OEM numbers across brands.
- Parts resellers verifying fitment and catalog listings.
- Researchers comparing how different manufacturers organize their parts data.
What it is not
Based on the available information, WebAutoCats.com is a reference and directory resource. There is no indication that it sells parts, processes payments, or requires an account. If you need to actually purchase a part, you would take the number you find here to a dealer or parts retailer.
How to use it
- Identify your vehicle's make, which determines the relevant catalog system (for example, BMW → ETK, Volkswagen → ETKA).
- Open the corresponding catalog through the site.
- Search by model, year, or part category to locate the OEM number.
- Note the number and verify fitment before ordering elsewhere.
The exact navigation depends on which catalog you open, since each system has its own interface.
Key limitation to keep in mind
The site is described as a "miscellaneous web resource," so treat it as a starting point for catalog lookups rather than an official manufacturer portal. Always confirm part numbers against a dealer or an authoritative source before relying on them for a purchase or repair.
