The Spearfish lot on 1st Avenue — a timber-fronted building with a green roof, pennant flags strung across the front and cars parked up to the door.

Spearfish & Belle Fourche, South Dakota

Everythingon the lot,on the site.

165 units photographed on two lots in the northern Black Hills — trucks, cars, skid steers, trailers, campers and side-by-sides. Locally owned, locally operated. No documentation or hidden fees charged.

No documentation or hidden fees. Locally owned, locally operated. 38 machines and 20 attachments. Cars and trucks from 1929 to 2025. We buy vehicles, machinery and ATVs. Two lots, a dozen miles apart.

Six departments

A little bit of everything, and a lot of Bobcats.

Their own line for the lot is “a little bit of everything”, and the count backs it up: a 1929 Model A and a 2025 Palisade are parked on the same gravel, and the biggest single department is not cars at all — it is 38 pieces of equipment and 20 attachments to hang off them.

The showroom floor — a dark Mustang and a red Beetle convertible parked indoors beneath a Conoco sign and a Hilltop Motel neon.A showroom wall covered in Gulf, Texaco and Conoco signs, with a traffic light showing green beside an open doorway.The needle of an old speedometer resting near sixty, with 60,653 on the odometer below it.

The room behind the glass

Most used-car lots don’t have a museum in them.

Walk into the showroom and the first thing you see is not a desk. It is a Conoco sign, a Texaco sign, a traffic light, a jukebox, and a Mustang parked next to a Beetle under all of it.

That tells you something useful before anyone has said a word to you. The people who fill a showroom with old gas-station signs are the people who will happily talk to you about a 1966 Ambassador convertible or a 1929 Model A — and they have both, sitting a few rows from the newest SUV on the lot.

  • Heith was amazing to work with. I got a 2002 Chevy 2500 Duramax and he was very honest about the truck and even fueled the truck up for me. Truck runs amazing. Any new car buyer or someone with a budget this is the best place to get your vehicle

  • I was in the market for a used Bobcat for the farm and when I found this s300 advertised on craigslist at Signature Auto Sales, I called Heith. He represented it very well, price was very fair and even negotiated delivery with me over the weekend! Highly recommend doing business here!

  • The sales team is extremely helpful and friendly, not pushy and forceful. It was a pleasant experience! We stopped and looked at the campers, they hooked up their personal vehicle to get power so we could see with the slide out. We stopped on a Saturday afternoon and made our decision on a Sunday, filled out the credit app and now have a great camper!

  • I just purchased a van from Ron at signature auto sales. I had a very positive buying experience. Since I was the whole way from Pennsylvania I had to make the deal and correspond by phone and email. Ron represented the vehicle very fairly to me. He went above and beyond his duty by bringing the vehicle to the airport for me and having paperwork and the vehicle all ready to go.

  • Traded and moved up 18 years for a good price on a Bobcat S62. Scott was great to work with over the phone. He even filled it, so my filled trade saved me extra at least 60 bucks.

  • Have bought 2 cars from Scott. Would highly recommend this place for great service and honest people.

Paying for it

Local banks, not a lender they own.

Financing runs through South Dakota credit unions and national banks, or your own financing if you would rather bring it. There is no in-house finance arm here taking a second bite, and the sticker is the number — no documentation fee, no hidden fee.

One thing worth knowing before you drive out: they do not take debit or credit cards.

Two lots, two numbers

Ring the lot the unit is on.

Stock turns daily, and the person who can tell you what a unit is really like is the person standing next to it. Ring either lot and they will tell you which one it is standing on today.
