THE SHORT ANSWER
Which parts of a scrapped car carry the most value?
The catalytic converter, first and by a distance, because it holds platinum, palladium and rhodium. After it come the engine and transmission when they still turn, then the copper-wound alternator and starter, then alloy wheels, straight body panels and intact glass. Underneath all of it sits the recoverable steel, which is the floor every offer starts from.
Catalytic converter
Highest single valueThe converter holds platinum, palladium and rhodium in its honeycomb. Those three metals trade well above the steel around them, which is why a missing converter changes an offer more than any other absent part. Say up front whether yours is still fitted.
Engine and transmission
High, if they turnA drivetrain that still turns over can be tested, rebuilt and resold as a unit. A seized engine or a transmission with no drive drops to the value of its metal. This is why whether the car starts is the second question after year, make and model.
Alternator, starter and battery
Steady valueAlternators and starters are copper-wound and rebuildable, so they resell as cores even when they have failed. The lead-acid battery goes to a regulated recycler rather than the scrap pile. All three are small, quick to remove, and commonly gone before a car is collected.
Wheels and tyres
Depends on the materialAlloy wheels carry aluminium value and resell as a set. Steel wheels go with the hulk. Tyres with usable tread resell; worn ones are a disposal cost rather than a credit, handled through a regulated stream. Say which you have on the car.
Body panels, doors and glass
Model dependentA straight door, tailgate, bonnet or wing sells to someone repairing the same model. Rust and collision damage remove that option and leave the weight. The full glass set — windscreen, side glass, rear screen — resells when it comes out intact.
Interior, electronics and lights
Varies widelySeats, infotainment units, instrument clusters and intact headlight assemblies all resell for common models. Water damage and cracked housings take them out of the resale stream. Mention any flood history, because it changes the whole interior at once.
The remaining shell
The floor under every offerOnce the parts come off, what is left is recoverable steel and aluminium priced by weight. A three-quarter-ton truck carries substantially more of it than a compact hatchback. This is the floor that keeps a vehicle with nothing resellable above zero rather than at zero.
