Auction snapshot
At the August 25, 2026 observation, the high bid was $640 with three bidders. The seller confirms seven Trimble R8 receivers and restricts purchasers to U.S. citizens or Lawful Permanent Residents.
The lot is not seven identical Model 3 units: only two may be described as probable Model 3, and the Pathfinder part is an antenna/accessory rather than another receiver.

How independent review worksHow evidence is classified
Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.
Photo Derived
Photo-derived
- Two receivers may be probable Model 3 units only.
- Photos do not establish calibrated or tested condition.
Manufacturer Context
Independent context
- The Pathfinder part is normalized as an antenna/accessory.
Lotcaliper Assumption
LotCaliper assumptions
- $5,800 conservative gross resale.
- $1,750 public maximum hammer, rounded down from the raw ROI ceiling.

Sensitivity and robustness
Survives
The published decision survives the selected downside check under the stated bounded assumptions.
$4,550 resale stress
- Max hammer
- $975
- Gross resale model
- $4,550
At the $640 observed bid, the stress case models about $1,228 profit and 46.5% ROI.
Higher-logistics sensitivity
- Max hammer
- $1,250
An additional $500 burden reduces the public ceiling to about $1,250.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $870 | LotCaliper assumption: 15% of modeled conservative resale proceeds. |
| Shipping | $700 | LotCaliper pickup, packing, and inbound-logistics reserve; not a GSA or carrier quote. |
| Testing Repair Reserve | $700 | LotCaliper cleaning, diagnostics, and functional-verification reserve. |
| Risk Buffer | $600 | LotCaliper reserve for collection, minor service, configuration, condition, and liquidity. |

Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
Risks and unknowns

Seller requires a U.S. citizen or Lawful Permanent Resident purchaser.
