Top 7 Things to Check Before Buying a Used Car in the GTA
Top 7 Things to Check Before Buying a Used Car in the GTA
Buying a used car in the GTA can be a smart move—prices are lower, depreciation is slower, and you can often get way more car for your money.
But if you pick the wrong one, you can also inherit someone else’s problems: hidden accident damage, major mechanical issues, or costly repairs a few months after you drive off.
At Green Auto in Vaughan, we see this every day in the shop. The good news? With a simple checklist and a bit of patience, you can avoid most of the common mistakes.
Use this guide before you buy a used car anywhere in the GTA.
1. Start With the Vehicle History
Before you even pop the hood, ask for:
Carfax or history report – Check for accidents, insurance claims, mileage inconsistencies, and branded titles (rebuilt, salvage, etc.).
Service records – Regular oil changes, brake jobs, and maintenance show the car was cared for.
Number of owners – Fewer owners often means a more predictable history.
🚩 Red flags: major accidents, inconsistent mileage, flood damage, or a long list of owners in a short time.
2. Do Basic Mechanical Checks
Even if you’re not a mechanic, you can spot obvious issues:
Fluids:
Engine oil should not be thick, burnt, or full of metal shavings.
Coolant should be clean, not rusty or oily.
Transmission fluid (if accessible) shouldn’t smell burnt.
Leaks: Look under the car for fresh oil, coolant, or transmission fluid on the ground.
Warning lights: When you turn the key, all dashboard lights should come on briefly, then go off.
If the Check Engine, ABS, or Airbag light stays on, something’s wrong.If you’re unsure, this is where a professional pre-purchase inspection at a shop like Green Auto can save you thousands.
3. Check Engine & Transmission Health
These are the most expensive components to fix or replace.
Engine:
Listen for ticking, knocking, or rattling sounds.
Watch for excessive smoke from the exhaust:
Blue smoke = burning oil
White smoke = possible coolant issue
Black smoke = running too rich (fuel problem)
Transmission:
On an automatic, shifts should be smooth, not jerky or delayed.
On a manual, the clutch should not slip or grind going into gears.
🚩 Red flags: harsh shifting, slipping gears, loud engine noises, or heavy smoke.
4. Inspect Brakes, Suspension & Tires
These affect both safety and driving comfort.
Brakes:
Listen for squeaking or grinding.
If the car pulls to one side when braking, there may be an issue with calipers or rotors.
Suspension:
Drive over small bumps – if the car bounces excessively or feels loose, the shocks or struts may be worn.
Clunking sounds over bumps can indicate worn suspension components.
Tires:
Check tread depth and even wear.
Uneven wear on the inner or outer edges can suggest alignment or suspension issues.
A quick inspection on a hoist at Green Auto can give you a clear picture of what you’ll need to spend on brakes, tires, and suspension after buying.
5. Look Closely at the Body & Frame
Body and frame damage can reveal old accidents or poor repairs.
Panel gaps: Uneven gaps between doors, hood, and trunk can show previous collision repair.
Paint: Mismatched paint shades or overspray around edges = repainted panels.
Rust: Focus on wheel wells, rocker panels, under doors, and the frame.
Surface rust is common in Canada, but deep rust or holes can be serious and expensive.🚩 Red flags: frame damage, heavy rust, or signs the car was badly repaired after a major accident.
6. Check the Interior & Electronics
You’re going to sit in this car every day—make sure everything works.
Seats & upholstery: Look for tears, burns, or heavy wear that doesn’t match the mileage.
Odours: Strong mould, smoke, or chemical smells can be hard to get rid of.
Electronics: Test:
Power windows & locks
Mirrors
Radio & Bluetooth
Backup camera
A/C and heat
All interior lights and dash controls
If the seller didn’t bother to fix simple things, they may have ignored major maintenance as well.
7. Take a Proper Test Drive
Don’t just drive around the block—spend at least 15–20 minutes in mixed conditions.
During the test drive:
Start from cold if possible – some issues only show up on a cold start.
Pay attention to:
Steering – does it pull, wander, or vibrate at highway speeds?
Braking – is it smooth and straight?
Engine – any hesitation, misfires, or lack of power?
Transmission – are shifts smooth and predictable?
If anything feels off, don’t ignore it. Make a note and have a professional take a look before you sign anything.
Final Thoughts: Protect Yourself With a Pre-Purchase Inspection
