What to Check on the Glass When Buying a Used Car

What to Check on the Glass When Buying a Used Car

The glass is easy to overlook when buying a used car, but a damaged or poorly replaced windscreen can cost you money and cause problems at rego time. Here is a quick checklist to run through in daylight.

1. Chips and Cracks

Look through the windscreen from inside and outside, and run your hand lightly over anything suspicious. Pay attention to the driver’s line of sight and the edges. See types of windscreen chips and cracks and whether a chipped windscreen can fail rego.

2. Has the Windscreen Been Replaced?

Compare the marking in the corner of the windscreen with the side windows. A different brand on the windscreen usually means it has been replaced — not necessarily a problem, but worth asking about. See car glass markings explained.

3. Signs of a Poor Replacement

• Mouldings lifted, twisted or missing
• Adhesive smeared on the glass or paint
• Scratches or bubbling paint around the windscreen frame — see rust under the windscreen
• Wind noise at speed — see wind noise after a windscreen replacement

4. Leaks

Check the headlining at the top corners and the footwell carpets for damp, staining or a musty smell. See why a windscreen leaks after rain.

5. Camera and Sensor Warnings

On cars with driver-assistance features, start the car and check for warning lights, and test lane-keep and automatic wipers on your drive. If the windscreen has been replaced, ask whether the camera was calibrated. Calibration costs vary by vehicle and are quoted separately; Aussie AutoGlass coordinates with specialist calibration providers where it’s needed.

6. Side and Rear Glass

• Windows go up and down smoothly — see window regulator repair
• Rear demister lines work
• No cracks or cloudy patches

7. Window Tint

Very dark aftermarket tint may not be legal. See window tinting laws in NSW.

Frequently Asked Questions

Is a replaced windscreen a bad sign?

No — windscreens are replaced all the time. What matters is that it was done properly and any camera was calibrated.

Can I negotiate on price for a chipped windscreen?

It is reasonable to factor in the repair. Stone chip and crack repairs start from $110; windscreen replacement starts from $330, depending on the vehicle.

Should I get the glass inspected before buying?

If anything looks off, an inspection is cheaper than a surprise later.

Does a cracked windscreen affect a pink slip?

Damage in the driver’s view can. See driving with a cracked windscreen in NSW.
