Most people have never been told this, and the ones who have usually heard it from someone with an interest in keeping it vague. Here's the honest version.
01Curb weight is the floor
A vehicle body is mostly steel, and steel is bought and sold by the tonne on a commodity market that moves weekly. Weight alone creates hundreds of dollars of difference between vehicle classes before anything else is considered.
02Non-ferrous metal is where the margin sits
Aluminium wheels, aluminium blocks and cylinder heads, copper in the wiring harness and starter, the radiator, the alternator. These are worth several times what plain steel is per kilo. A car with alloy wheels and an aluminium block is worth meaningfully more than an identical car with steel wheels and a cast-iron block.
03The catalytic converter is its own line item
It contains platinum, palladium and rhodium, and the value varies enormously by vehicle. A converter off a large truck can be worth more than the rest of the car. This is also, bluntly, the number a lot of buyers hope you don't know about. Converter theft is widespread in Calgary — if yours has been cut off, that lowers your number, and we'll say so rather than quietly adjusting the payment when we arrive.
04Reusable parts come off the top
Even on a car headed for scrap, there might be a good alternator, a working window regulator, a clean set of doors, or a rear differential that somebody in Okotoks needs next Tuesday. Anything with a second life is worth more as a part than as metal, and that's reflected in what we can pay.
05Completeness matters more than people expect
A vehicle that's already been picked over is worth less. If you've pulled the engine, sold the wheels and taken the seats out, you've removed most of what we were paying for. We'll still take it — the number just won't be the same.
