Quality Parts. Honest Service. Lasting Value.
The HIS German Auto Parts family of brands are dedicated to a set of core principles that reflect the ethics of its founders and employees. We source quality products to ensure dependability and safety. We strive to maintain transparency in what we do and why we do it. And we continually seek new ways to help not just our customers, but also our community.
Who We Are
Since its founding in 2018, HIS German Auto Parts has been providing affordable replacement parts for popular German car brands to customers and enthusiasts all around the world. We started off with a selection of Audi, Volkswagen, BMW, and Mercedes-Benz parts going back to the late 1980s: many of which were rare and discontinued parts.
In the past few years, we have been fortunate enough to form partnerships with very skilled and knowledgeable people that have allowed us to branch out and help provide parts to car owners and enthusiasts across several different brands.
Continue reading below to find a list of our current brands and see the different offerings they provide, while still sharing the core mission of HIS German Auto Parts: providing customers with quality products at great prices and excellent customer service.
Our Brands
Discover the different brands under the HIS umbrella, each with its own specialty to best meet customer needs.
Adsitco
For nearly 50 years, the Adsit Company has been lending their parts expertise to their customers. After years of close collaboration with the Adsit team–and learning much from them–we were able to acquire the company in 2020.
With a renewed customer-centric approach, the Adsit team will continue serving the Mercedes community to provide all manner of parts for these classic vehicles.
If you own a Mercedes-Benz, from the vintage 1960s models all the way up to the newest models today, Adsit is the place to keep your vehicle running great and looking sharp!
Partwise
Launched in 2025, Partwise provides OEM and OE-quality replacement parts at fantastic prices! Providing parts for our widest selection of vehicles yet, Partwise is able to offer prices better than you can find at nearly any other auto parts store.
As dependent as we are on our cars to make a living, replacement parts and repairs aren’t cheap. Partwise was conceived to help combat that. If you need car parts fast and on a budget, PartWise.com has you covered!
Mercedes Part Vault
An extension of Adsitco’s dedication to Mercedes parts, the Mercedes Part Vault eBay store is a way to combat the sometimes dubious nature of shopping for used auto parts online.
With a reduced focus on studio-quality product photos, we are able to speed up the time it takes to list the products that our customers are looking for and put more emphasis on transparency. Each product listing is unique with detailed images that allow our customers to inspect the exact part they will receive: no guesswork, no surprises.
Frequently Asked Questions
Have a question? We’ve compiled answers to the most common inquiries to save you time and provide easy access to essential info. These FAQs cover all brands under the HIS German Auto Parts umbrella, including Adsitco, Partwise, and Mercedes Part Vault.
I'm looking for a Mercedes part, but don't see it listed online - what do I do?
Due to the multitude of Mercedes parts available, not everything is listed online yet. The best thing to do is contact Adsitco by phone or email and describe the part you’re looking for. Our Mercedes parts experts will help you find the part you need based on the year and model of your vehicle.
Where do I go to find parts for my Audi, Volkswagen, or BMW?
Aside from the selection of parts available in our eBay store, you can search Partwise.com for the parts you’re looking for. We are continually adding more products, so be sure to check back to see our latest offerings!
I see used Mercedes parts listed on both Adsitco and Mercedes Part Vault - what's the difference?
Since both brands focus on Mercedes-Benz parts, that is bound to happen. Historically, Adsitco has listed used parts with a recurring product listing, with a photo representative of the used product. Since Mercedes Part Vault is exclusively used parts, we are able to provide individual listings for each individual part we have in stock, leading to more accurate images and sometimes lower prices.
I see some items with a "Core Price" - what does that mean?
A “core” refers to an old unit in your vehicle that is meant to be replaced. For example, if you are replacing your fuel pump, the old non-working fuel pump in your car would be considered a “core”. The core price, or core deposit, is a temporary charge you pay at the time of placing the order that is refunded once you send back your core. It is intended as both an incentive to send back your core so that it can be rebuilt and sold to a future customer, or is used to purchase a core elsewhere if you don’t have one.
