The 5 Places for the Best Car Auctions in Bangkok


We assessed this based on the range of vehicle types, brands, and models offered by the car auction companies.


For a smooth transaction, good customer service is essential. We based this on each company’s response to inquiries, concerns, biddings, and post-purchase services.

Payment Options

We also considered the different avenues for payments offered by each company to make the process easier. Flexible payment terms are a bonus, too!


Biddings tend to reach high prices at times so we considered the additional fees and taxes a company might charge its bidder or customers.

Motto Auction is one of the leading car auction service providers in Thailand. Interestingly, it is the rebranded entity of the renowned Manheim brand, a well-known and trusted company for car auctions.

Although it was founded eighteen years ago, this company is at the forefront of innovative solutions. Through its apps and online bidding platforms, it combines global knowledge with Thai market expertise to provide a convenient method of holding car auctions in the country.

What we like most about Motto Auction are its easy-to-understand and navigable website. Unlike most of the other car auction service providers on this list, it provides an English mode, making the user experience better for its non-Thai customers.

Moreover, it has an impressive Power Search system that enables customers to search for a vehicle depending on the province, type, model, brand, gear, or mileage. We also like the nifty auction calendar, which shows the kind and number of vehicles available per date.

On the other hand, we hope it also offers the same convenience to foreigners on site. We were disappointed to learn from our surveys that several non-Thai residents found it difficult to communicate with the staff in its office at Prawet.

Nonetheless, we appreciate the convenience Motto Auction provides its customers through its online bidding platform, especially the Simulcast System, which shows the bidding event in real-time.

Alliance Auto Auction is an award-winning car auction service provider established in 2005. For the past seventeen years, it has built a good reputation and trustworthy image in the Bangkok automotive scene.

It is noteworthy that Alliance Auto Auction has gained wide recognition, including two national awards, the 2012 Integrity Award and the 2015 Good Governance Award. 

Furthermore, we found Alliance Auto Auction a reliable service provider through its partnership with reputable financial institutions. Customers who need credit support and flexible payment terms can apply with Thanachart Bank and Toyota Leasing.

It is also noteworthy that all auctioned vehicles are inspected by a third-party provider, One2Car, a well-known used car dealer in Thailand. Furthermore, the chassis structures are tested through the iTest Car-O-Liner from Sweden, with a 6-month certificate and buy-back guarantee.

Another thing we liked about Alliance Auto Auction is that it holds regular onsite auctions every Monday at 11:00 AM. While the list of vehicles for auction is unavailable on its website, its Facebook page is a reliable way to check the available cars.

Upon checking the list, we were glad to find a variety of vehicle types, brands, models, and conditions. Customers are not limited by the available options at every auction.

On the downside, we had difficulty understanding the auction process since its website is not available in English. However, its staff provides a quick response and clear answers to inquiries done on Line and Facebook messenger.

We also appreciate its fast refund process for the deposit. Compared to the other car auctions in Bangkok, which can take two weeks to process refunds, Alliance Auto Auction returns the cash in less than seven days.

Finally, vehicles purchased at Alliance Auto Auction can be serviced at a discounted rate at any ACT branch in Thailand, and this is a plus point in our books!

  • Provides a comprehensive car list for every auction schedule
  • Has a financing service
  • Has online and onsite auctions
  • Has many car models and vehicle types


  • No English support on the website

Next on our list is Sia Auction or Siam Inter Auction. In its eighteen years in the industry, this auction service provider has sold over 400,000 vehicles and more than 100,000 bidders.

We found that it has one of the most varied selections of vehicles for auction in Bangkok. It regularly lists cars, pickup trucks, motorcycles, big bikes, buses, trucks, combine harvesters, and other equipment in various conditions ranging from old ones to almost new.

Furthermore, it has a vast facility in Saphan Sung, Bangkok 31 warehouses all over Thailand, where it houses thousands of vehicles. The onsite staff is also helpful – unlike its website, which is complicated to navigate and understand.

On the other hand, we appreciate the detailed calendar on its website, where a comprehensive list of vehicles is shown for every auction. The detailed information for each car is something that we were glad to see.

Aside from its wide online popularity, what solidified our trust in Sia Auction is its previous partnership with the Thai Customs Department. In 2020, this company was tapped by the department to host the annual car auction in Khlong Toei, Bangkok.

Finally, we like that Sia Auction assists its customers in need of a loan. We have to mention that if applying for credit, the customer must apply for it at least three days before the auction.

  • Has two locations in Thailand
  • Affiliated with over 20 financial institutions and companies
  • Great for heavy machinery, trucks, and trailers


  • No online English support
  • Two hours away from Central Bangkok via bus lines

If you are looking for semi-trailers, heavy equipment, tractors, and trailers, this car auction is for you! Aside from that, Inter Auction is a reliable source for the usual cars and motorcycles ranging from budget to luxury models.

Established in 1998, Inter Auction Company first opened at the Carrefour Department Store. As it grew, the company moved to the Mueang Pathum Thani District in a larger facility, which can accommodate up to 12,000 vehicles.

So far, this company has the most impressive variety of vehicles available in an auction. In a single schedule, it has almost 200 cars with bidding prices that start as low as 110,000 Baht to 1.5 million Baht.

We like that this variety makes it easier for customers to engage in business since they provide vast options. Interestingly, Inter Auction Company even lists Ink Jet printers and film compression machines.

Like the other auction sites on this list, Inter Auction Company provides onsite and online buying and selling platforms. However, its location in Mueang Pathum Thani is not easily accessible by public transport, making the online auction more convenient.

As for their service, we appreciate the good feedback we received from our surveys. Many customers have commended the approachable and helpful staff who were hands-on with the entire process, from registration to the transfer of documents.

Finally, we found it noteworthy that Inter Auction Company is affiliated with more than 20 financial institutions and companies. Its solid track record, reputable partners, and long history in the industry earned our trust.

  • Has nine locations in Thailand
  • Has been in the industry for 31 years


  • Customer service needs improvement

Union Auction has been conducting car auctions in Thailand since 1991. Since then, it has extended to auctioning motorcycles and other assets, such as shares, land and houses, appliances, luxury goods, and furniture.

Aside from its main branch in Bangkok, Union Auction also has offices in four provinces: Ubonratchathani, Udonthani, Surajthani, and Hadyai. We like their varied locations because having those enables more people to access their services.

We also found it impressive that Union Auction has been granted licenses to conduct auctions for various government agencies. Its notable government affiliations include the Office of Narcotic Control Board, the Anti Money Laundering Office, and the Customs Department.

Moreover, Union Auction was the company entrusted by the Thai government to conduct the 4G auction at the Office of The National Broadcasting Telecommunications Committee. 

Other notable partners of Union Auction include Toyota Leasing, SCB, Krungsri Auto, Kubota, TTB, and Summit Capital. 

Despite its long experience in the industry and impressive partners, we were disappointed to learn that its customer service needs improvement. According to the customers we surveyed, we received a lot of mixed opinions.

While its online support is commendable, several clients had issues with the on-site staff during the delegation and delivery of the vehicles. On the other hand, we noticed that this issue frequently occurred when the company was handling massive transactions.

With this in mind, we hope that Union Auction can improve its services by updating its protocols to accommodate all its customers on busy days.
