Field Notes

What our customers say

Alice.K

📍 Antioch TN

We had a hard time reaching someone after we won the bid. We understand there were likely a high number of calls, but the wait wasn’t ideal. After about two hours, they finally contacted us and explained the next steps. I decided to pick up the vehicle myself, and they coordinated everything with the vendor. We proceeded with an ACH transfer, and they confirmed the funds after 48 hours and began working on the title release. Overall, the car was great. It was about a 7/10 experience, but we understand the situation.

Jennifer.C

📍 LAREDO TX

Not my first time purchasing from them, and they have a great team indeed. They had another great offer, so I decided to buy from them for the third time. I recommend them 100%!

Alex.W

📍 Wauwatosa WI

I was skeptical at first. You know what they say: if something seems too good to be true, it probably is. But this experience proved me wrong. The whole process went smoothly, and although I had my doubts in the beginning, they provided everything I requested before we moved forward. Once I was satisfied, I purchased the vehicle. About five days later, after they completed everything on their end, I picked up my Range Rover with my gate pass. I’m really happy I chose them because I saved a significant amount of money. I highly recommend them to anyone looking for a smooth, professional, and trustworthy car-buying experience.

Andrew.L

📍 Odessa TX

So incredibly happy with this purchase! Bought a 2020 Lexus RX 350 for my wife. Our credit union completely messed up our wire transfer and sent it with the wrong routing info on the final payment day. I was panicking that the auction would cancel the sale . The customer service agent stayed on a three-way call with me and my bank for 45 minutes to sort out the tracking and secure the vehicle. Amazing support!

Arnold.C

📍 Danville IL

got a loaded 2023 f-350 dually diesel to pull my horse trailer. this truck is an absolute monster. taking off one star because the gate crew took over two hours to find the keys and bring it out to my trailer on pickup day. but the truck itself is mint—spotless interior, zero blowby, and pulls like crazy

Jeremy.K

📍 VALLEY VILLAGE, CA

Beyond thrilled with our purchase! Got a 2023 G Wagon for my daughter's graduation present. Our credit union had a massive glitch and failed to send the wire transfer before the 24-hour payment deadline. I panicked thinking we’d lose the car . The support agent, Christian , stayed on the line with me and my bank for almost an hour, extending our payment window manually until it cleared. Incredible customer service!

Anthony.W

📍 Chicago IL

Still can't believe there's a 2020 Shelby GT500 sitting in my driveway right now. The entire auction process from bidding to scheduling the enclosed transport was flawless. The car is literal perfection. 5 stars all day long.

Adam.B

📍 Pensacola FL

copped a 2022 audi RS5 sportback for $56k flat. everything was golden until i noticed a weird vibration over 70mph during my drive home. took it to my mechanic, turns out two of the 20-inch wheels were slightly bent... prob hit a massive pothole with the previous owner. auction group refused a refund because wheels count as wearable/road wear under their rules, but the manager threw in a $400 credit toward my next auction buy. got the wheels straightened for $300 locally so i actually made out fine. car pulls like a freight train anyway

Mark.C

📍 Denver CO

bro u gotta be kidding me. bought a 2025 Escalade Esv and the delivery guy drops it off with NO GAS. literally bone dry had to walk to the chevron with a gas can. car is fire tho and support gave me a $50 voucher for my next bid cuz i complained about the gas thing. still kinda annoying but whatever

Kim.V

📍 Los Angeles CA

My car got totaled last month and insurance didn't give me enough to buy a decent replacement at today's dealership prices. A friend recommended this auction. I managed to get a 2019 Hyundai Elantra with only 40k miles on it well within my budget. It’s been 3 weeks and the car is running perfectly. Such a lifesaver.
