How to appraise a used car trade-in: a dealer’s step-by-step checklist (Canada)

What should you check before walking out to the car?

Most appraisal mistakes start at the desk, not on the lot. Before you touch the car, pin down exactly what it is and whether it can be sold cleanly.

• VIN and trim. Check that the VIN on the dash plate matches the door-jamb label and the registration. Decode it to get the year, engine, drivetrain and, where the decode allows, the trim. Confirm trim from badges and equipment (seats, wheels, screen, towing package), because two trims of the same truck can be thousands of dollars apart.
• History. Pull a Canadian vehicle history report. Look for accident claims, registration in other provinces or the US, and any brand such as salvage, rebuilt or non-repairable. A US history means the odometer may have been in miles at some point.
• Liens. Search the provincial personal property registry (Alberta and BC each run one). An open lien is not a deal-breaker, but the payout has to be confirmed and handled on the bill of sale.
• Recalls. Check Transport Canada’s recall database or the manufacturer’s site for open recalls. They rarely change value, but you will want them done before retail.
• Questions for the owner. How long have they had it, any accidents, recent repairs or warning lights, how many keys, and are winter tires included? A missing second key or fob is a real recon cost.

How should you do the walk-around?

Start at the driver’s front corner and go clockwise, stopping at the eight points of a standard walk-around: front, front corner, side, rear corner, rear, and the same on the other side. Then go back for close-ups of anything you found.

• Dents and dings. Look down the length of each side in raking light. Reflections bend around dents that are invisible straight on.
• Prior repairs. Uneven panel gaps, paint that doesn’t match next to its neighbour, overspray on rubber seals and masking lines all point to bodywork. A paint thickness gauge confirms it: a panel reading well above its neighbours has been refinished.
• Glass. Windshield chips and cracks are routine on Alberta cars. Check whether the glass brand marks match on every window; a different one means a replacement.
• Tires and wheels. Measure tread on the inside, middle and outside of each tire. Uneven wear points to alignment or suspension work. Read the DOT date code and note curb rash.

Photograph as you go. Photos settle disagreements with the customer and with your own sales team later.

What should you check underneath and under the hood?

Get low with a flashlight on every car. Look at the frame rails, rocker panels, brake and fuel lines, subframes and exhaust for rust; at the engine, transmission and differentials for leaks; and at the CV boots and suspension bushings for tears and cracks. On Canadian cars, salt damage is usually the biggest recon surprise, so our road-salt damage guide has the full list of places to look.

Under the hood, check oil level and colour (milky oil can mean coolant in the oil), coolant level, belts and hoses. Be wary of a freshly pressure-washed engine bay on an older vehicle: it can hide leaks.

What does the interior tell you?

• Smell first. Smoke, pets and mildew are expensive to remove. Mildew can also mean a water leak from a windshield seal or blocked sunroof drains.
• Wear against km. A worn driver’s seat bolster, shiny steering wheel and worn pedal rubber on a low-km car deserves a closer look at the odometer story.
• Warning lights. At key-on, every warning light should come on for the bulb check and then go out. A check-engine light that never comes on at all can mean a disabled bulb.
• Everything that switches. Heat, defrost, A/C, heated seats, windows, locks, remote start, camera and sensors. In a Canadian winter a weak heater or defrost is a must-fix, not a nice-to-have.

Why scan every trade-in with an OBD-II reader?

A scan takes about as long as reading the odometer and tells you what the dashboard won’t. Read stored, pending and permanent codes, the readiness monitors, and the distance and warm-ups since codes were last cleared. A light that is off proves nothing on its own: clearing codes turns it off for a while, and the readiness data is how you tell. Our guide on spotting recently cleared codes explains how to read it.

Also compare the VIN reported by the engine computer with the VIN on the car (a mismatch suggests a swapped computer), and check battery voltage. Appraise’s OBD scanner does all of this from a Bluetooth reader and flags anything suspicious in red.

What should the test drive cover?

Use the same short route every time, including some highway speed, so you compare cars against the same baseline.

• Cold start if you can. Ask the customer not to warm it up. Listen for ticking, rattles or smoke in the first seconds.
• Transmission. Smooth shifts cold and warm, no flare between gears, no clunk into drive or reverse.
• Brakes and steering. Pulsation under braking, pulling to one side, play or clunks over bumps.
• 4x4 and AWD. On trucks, engage four-wheel drive where it is safe to do so. A transfer case that won’t engage is an expensive find after the deal.
• Features at speed. Cruise control, driver-assist warnings and wind or bearing noise.

How do you turn findings into a recon number?

List every item you found with a cost next to it: mechanical repairs from the scan and the drive, dents and paint, tires, glass, keys, detail, and anything needed to pass your safety or mechanical fitness inspection. Use your own vendor and shop rates so two appraisers reach the same total. When you can’t verify something (a car you can’t drive, a code you can’t confirm), add a clearly labelled contingency instead of hoping. The reconditioning cost guide shows how to estimate each category.

How do you value the car and set the max buy?

Find retail comparables that match year, make, model, trim and drivetrain, with similar km, in the area you actually sell into. Adjust for km differences, drop outliers like branded titles, and remember that asking prices are higher than selling prices. That gives you expected retail. Then work back:

Check the result against wholesale too: if you could not retail the car, what would it bring? The guides on calculating max buy and wholesale vs retail vs trade-in value go deeper.

How do you present the number to the customer?

Set your offer below the max buy, write it down, and show the reasons: comparable cars, the recon the car needs and anything the scan found. Customers push back on numbers they can’t see behind. Our guide to presenting a trade-in offer covers what to show and what to keep private.
