What actually moves the hammer price on a salvage lot
Two nearly identical write-offs can sell £1,000 apart. The real factors that move a salvage auction price, and where to see actual sold comps rather than guess.

Same year, same model, different money
Watch enough salvage auctions and you will see it constantly: two examples of the same model, similar mileage, sell hundreds or thousands apart. The category on the listing explains some of that gap, but not all of it. A handful of other factors move the price just as hard, and knowing them is what separates a bidder who reads a lot correctly from one who is just guessing off the headline damage photo.
Category sets the ceiling, damage location and type set the real price
Cat N buyers pay more than Cat S buyers for the same model, on average, because the structural risk and re-registration hassle simply are not there. But within a category, where the damage sits matters more than how it looks in one photo. Front-end damage worries bidders more than rear-end, because it raises questions about crash structure and mechanicals even on a Cat N. Flood and all-over damage is priced the most cautiously of all, because it is the hardest to fully inspect from listing photos alone.
Mileage, desirability and parts availability
A low-mileage example of a model people actively want pulls a premium even with worse cosmetic damage, because buyers are bidding on the underlying car, not just the crash. The flip side is parts availability: a common model with a healthy breakers' market for panels and mechanicals is cheaper to fix and therefore supports a higher bid, while a rare or recently-facelifted model with scarce parts gets bid down because repair cost and delay both go up.
Documentation and run-and-drive status
A listing with a clear damage report, a run-and-drive confirmation and a full set of photos consistently sells for more than the same car described thinly, because it removes guesswork that would otherwise get priced in as risk. A car marked run and drive removes the biggest unknown of all, whether the engine and drivetrain actually work, and typically commands a real premium over an identical non-runner.
Where to see the real numbers instead of a rule of thumb
Every rule above describes a direction, not a figure, because the actual gap moves with the wider market week to week. We log every lot analysed on Salvage Prophet and revisit it after the auction closes to record the real final bid, building a genuine sold-price database rather than an estimate. The median sold price for a model is free to check, with no account needed, and the individual sold lots behind it can be searched by make and model for 5 credits, no subscription, for actual recent comps on the exact car being bid on, which beats any rule of thumb in this guide.
