What to Check Before Buying a Used Car: A Practical Inspection Guide

When shopping for a used car, looks can be deceiving. A shiny exterior doesn't always mean the vehicle is in great shape. That’s why knowing what to check — and what to ask — before buying can save you from costly repairs and regrets down the road.

At Waltham Auto Gallery, we want every customer to feel confident behind the wheel. Here’s a practical checklist to guide your inspection and make your car buying experience safer and smarter.


1. Exterior Condition

Start with a walkaround. Look for signs of:

  • Rust near wheel wells or under doors

  • Uneven paint or body panel gaps (could indicate accident repairs)

  • Cracks or chips in the windshield or lights
    Check that all doors, windows, and the trunk open and close smoothly.


2. Tires and Suspension

Check for:

  • Uneven tire wear (may indicate alignment issues)

  • Tire tread depth (should be more than 2/32”)

  • Bounce test: Push down on each corner — the car should rebound once, not keep bouncing


3. Under the Hood

Even if you're not a mechanic, look for:

  • Fluid leaks (under the car or around the engine)

  • Corrosion on battery terminals

  • Oil condition (check the dipstick — it should be golden-brown, not sludgy or black)

Ask if you can hear the engine while it’s running. It should idle smoothly and not make knocking or ticking noises.


4. Interior Features and Comfort

Sit inside and check:

  • Dashboard lights (no check engine or airbag warnings)

  • Functioning of A/C, heat, radio, and all buttons/switches

  • Seat adjustments and seatbelt operation

A clean interior often reflects how well the car was maintained overall.


5. Test Drive Experience

Always ask for a test drive. Pay attention to:

  • Acceleration, braking, and steering response

  • Any strange noises, vibrations, or delays

  • How the car handles bumps and turns

Try to drive on both local roads and highways if possible.


Pro Tip: Ask if the vehicle has been inspected by a third-party mechanic or if a pre-purchase inspection is allowed. At Waltham Auto Gallery, we welcome questions and transparency — and all our vehicles go through a rigorous inspection before being listed.
