A 4x4 Suburban that already has a fuel-injected LS, priced about 27% under the middle of driver sales.
1971 Chevrolet Suburban K20
Why we picked it
Why we picked it: the VIN prefix (KE26) points to a factory four-wheel-drive, three-quarter-ton V8 Suburban, which is the variant builders look for. The dealer says it has an updated drivetrain built around a fuel-injected 5.3 V8 and an automatic, a solid body with older paint, and an interior that was restored at some point and is still in good shape.
At $29,050 it is priced near the bottom of what driver-quality 1967-72 Suburbans have sold for, and most of those comps still had their original carbureted engines.
The value check
The seller is asking $27,550. Comparable cars in the same condition have sold for $27,250–$52,800, so the middle of the market is about $40,025. That put this car 31% under.
Driver-grade 1967-72 Suburbans sold for about $27k-$53k over the last year; a 4x4 K10 Suburban brought $60,500 and the fully built examples go far higher.

What to check
- The dealer notes rust in the rockers; also check cab corners, the rear quarters around the wheel wells, the tailgate and the floors under the rear seat
- Ask which transmission and transfer case are behind the 5.3, how the swap was wired (standalone harness, PCM tune) and whether the gauges work
- Mileage on this dealer's site is a placeholder; ask for the real odometer reading
- Title status is not mentioned; sold as-is. Confirm a clean title and arrange an independent inspection
- The dealer page shows two addresses (Brookings and White, SD); confirm where the truck is
Making it drive like new
With an LS already in place, focus on brakes (front disc conversion if it still has drums, plus a dual master cylinder), a spring-over or quality leaf pack with modern shocks, power steering box service, and a full rocker and cab-corner repair before paint.
