10 Critical things to
CHECK
before buying a
Used Car
1. Engine Oil Level and Condition
Pull the dipstick, wipe it clean, and reinsert it. Oil should be between the minimum and maximum marks and amber in color—not black or sludgy. Black, thick oil indicates poor maintenance.
2. Brake System
Look through the wheel spokes at the brake pads. They should be at least ¼ inch thick. Check for uneven wear, grooved rotors, or rust. During the test drive, brakes should feel responsive, not spongy.
3. Fluid Levels
Check coolant (should be bright green/orange, not rusty brown), transmission fluid (bright red, not dark brown), brake fluid, and power steering fluid. All should be at proper levels with no leaks underneath.
5. Battery
Check for corrosion on terminals (white, blue, or green buildup). Terminals should be clean and securely connected. Start the engine—it should crank smoothly. Headlights and interior lights should be bright.
4. Tires and Wheels
Use the penny test: insert a penny into the tread with Lincoln’s head upside down. If you see the top of his head, tread is too shallow. Check for uneven wear, cracks, bulges, and tire age (should be less than 10 years old).
6. Belts and Hoses
Inspect the serpentine belt for cracks, fraying, or glazing. Check all visible hoses for cracks, leaks, bulges, or soft spots. Hoses should feel firm, not mushy or brittle.
7. Suspension and Steering
Press down hard on each corner of the car—it should bounce once or twice, then settle. Steering should feel responsive. Listen for clunking sounds over bumps. The car should track straight without pulling.
8. Exterior Paint and Body
Look for consistent paint color and thickness across all panels. Mismatched paint suggests accident history. Check for rust, especially on the undercarriage and wheel wells. Panels should align properly.
9. Interior and Electronics
Check seats for tears or excessive wear. Test all power windows, locks, AC/heat, radio, and wipers. Dashboard should not be cracked or warped. Sniff the interior—musty smells indicate moisture or mold.
10. Test Drive
Start the car from cold—it should start smoothly. Accelerate gently; transmission should shift smoothly. Brakes should be responsive. Listen for engine knocking or unusual sounds. No warning lights should be on the dashboard. Drive at various speeds and test parking.
