1950 Chevrolet 3100 5-Window Pickup

Why we picked it

This 1950 Chevrolet 3100 five-window pickup is selling in the same Cheyenne, Wyoming estate auction as the Mustang. The listing says frame-off restoration, inline six, runs and drives, under 600 miles since, and clear titles. A 1950 Laycock one-horse trailer is included in the lot. The high bid is $11,500 after 29 bids, and the sale ends November 19.

Why we picked it: refurbished and restored stock-six 3100s have been selling for about $17,500 to $30,000. With the premium the truck is at $12,650 today, about 47% under the middle of that range. There are three weeks left, so expect it to rise.

The value check

The current bid is $11,500. Comparable cars in the same condition have sold for $17,476–$29,960, so the middle of the market is about $23,718. That put this car 52% under. Bids usually climb in the final hours, so the discount will likely shrink.

Stock-engine 1949-53 Chevrolet 3100s in refurbished or restored driver condition sold for $17,476 to $29,960 on Hagerty Marketplace between January 2025 and July 2026. The $11,500 bid plus the 10% premium ($12,650) is about 47% under the midpoint, but bids usually climb.

Where the numbers come from:

• Hagerty: 1953 3100, original 235, restored, $29,960 (Jan 2025)
• Hagerty: 1949 3100 5-window, refurbished, $26,750 (Jul 2026)
• Hagerty: 1952 3100, 235, refurbished, $17,476 (Apr 2026)

What to check

• Bids usually climb before the close; the deal only holds if it finishes well under about $20,000.
• 10% buyer's premium (3.5% extra by card); sold as is, where is; local pickup only; preview by appointment on November 14.
• The listing gives no VIN and no detail on who did the restoration. Ask for photos of the frame, cab corners, floor, door bottoms and bed wood.
• The mileage field shows 00596 and the description says 589, so treat it as miles since restoration.
• Confirm both titles (truck and trailer) are clear and in the seller's name.

Making it drive like new

Advance Design trucks take well to a Mustang II-style IFS crossmember with front discs, power steering and a 12-volt system. Keep the six with a dual-carb head and headers, or drop in a small-block with a T5 or 700R4 and an open-drive rear axle for highway gearing.

7 builders make a complete chassis for the 1947–54 Advance Design pickup (3100). Compare them side by side, along with what it takes to stiffen the factory frame.
