Mercedes M Class rear window price, by year
Price variation reflects the generation and trim level of your M-Class — earlier models with basic toughened glass are the most straightforward to replace, while later variants with integrated antennas, alarm wiring, or privacy tint carry higher costs due to the complexity of matching those features. Solar-control glass and heated panels also influence pricing.

What to expect during your Mercedes M Class rear window replacement
Booking your M-Class rear-window replacement is a straightforward four-step process.
- 1
Start with an instant online quote using our guided quiz — identify your model year and options in about 60 seconds.
- 2
Complete your booking in under two minutes, choosing mobile (at your address) or workshop fitting.
- 3
We match you with a technician near you, who carries out a parts check before the job to confirm the exact glass variant.
- 4
On fitting day, the fitter removes the shattered original window and bonds the new glass in place, typically within 30–60 minutes of active work.
- 5
Glass shards lodge in places fitters can't always reach — we recommend a professional valet afterwards for a thorough interior clean.
- 6
Your replacement is covered by a two-year warranty on workmanship and glass quality.
From quote to fitted glass, the entire process is designed to be quick, transparent, and backed by our network of trusted local technicians.
Mobile fitting or workshop visit for your M Class?
Most M-Class rear-window replacements are carried out mobile at your address — the technician brings everything needed to fit the glass and clear accessible shards. Because rear windows are not bonded to structural ADAS cameras (unlike windscreens), there is no calibration requirement after fitting.
You can always choose a workshop appointment if you prefer, but there is no safety or technical reason to require one for rear-window work on the M-Class.
We confirm the specific answer for your vehicle when you book.
What features does your M Class have?
Tap a feature to see what it is, how to spot it on your car, and how it affects glass replacement. We confirm the exact match for your vehicle when you book.
Antenna4
1998–2026On the Mercedes M Class: fitted on every one of the 4 rear window variants we list; model years 1998–2026.
What it means
An aerial laminated into the rear glass for radio, DAB, or navigation reception; the replacement must carry the matching antenna print and connector.
On your Mercedes M Class
Standard on all current M-Class models with integrated glass systems; confirmed during the parts check at booking.
Heated Rear Windscreen4
1998–2026On the Mercedes M Class: fitted on every one of the 4 rear window variants we list; model years 1998–2026.
Heated rear windscreen with integrated wires clears mist and ice when you switch on the demister.
What it means
A heated rear windscreen contains fine heating wires embedded within the glass. When you activate the rear demister, an electrical current passes through these wires, warming the glass and melting ice or condensation. This feature is particularly useful in cold or damp weather, improving rear visibility quickly. The heating grid is integral to the glass and connected to your vehicle's electrical circuit via connectors at the base of the windscreen.
How to tell
Look at the rear windscreen from inside the vehicle — you will see a fine grid of horizontal lines across the glass, typically bronze or copper in colour. On the dashboard or steering wheel stalk, there will be a dedicated rear-demist button, usually marked with a windscreen symbol and heating lines. If in doubt, ask your vehicle's service centre or consult your handbook.
Replacement impact
Replacement rear windscreens with heated grids are widely available as original-equipment aftermarket or dealership parts. The new glass must include the factory heating grid and electrical connectors intact. The technician will reconnect the heating circuit to your vehicle's rear-demist switch. Heated rear windscreens are bonded glass, so adhesive cure time applies; drive-away time will be confirmed by the fitter on the day.
Grey Privacy3
1998–2015On the Mercedes M Class: fitted on 3 of the 4 rear window variants we list (75%); model years 1998–2015.
Dark grey tint on rear windows provides privacy and reduces interior heat and glare.
What it means
Dark grey tint, formally known as privacy glass, is a factory-applied tint created through a deep-dipping process during glass manufacture. The pigment is infused into the inner surface of the glass, darkening the rear windows (and sometimes rear doors) significantly more than the front. This reduces heat transmission, minimises glare, and obscures the interior from outside view. It's standard on the rear half of many modern vehicles.
How to tell
Compare the rear side windows and rear window (backlight) to the front side windows — the rear glass will be noticeably darker. Check your vehicle documents or ask your dealership service centre if you're unsure whether your car left the factory with privacy glass.
Replacement impact
Dark grey tinted glass must be sourced from the Original Equipment Equivalent (OEE) or dealership to ensure colour and transmission match your vehicle's existing rear glass. The tint is integral to the glass itself, not a surface coating, so aftermarket non-tinted glass will look visibly mismatched. Replacement does not require any calibration and follows standard bonded-glass cure times for rear windows.
Brake Light2
1998–2026On the Mercedes M Class: fitted on 2 of the 4 rear window variants we list (50%); model years 1998–2026.
A brake light integrated into the rear window glass itself, requiring a matching replacement to reconnect the original lighting circuit.
What it means
A brake light integrated into the rear window glass is a lighting element built directly into the glass panel during manufacturing. Rather than using a separate lamp cluster mounted to the vehicle body, the light circuit is routed through conductive elements — typically a silkscreen pattern, wire network, or bracket assembly — embedded in or bonded to the glass itself. When you brake, this integrated light illuminates to warn following traffic. It combines functionality with design integration, reducing the number of separate components on the rear of the vehicle.
How to tell
Check your vehicle's rear window for a visible pattern of fine lines or wires running across the glass, usually near the top edge or spanning the upper portion. Look at your vehicle's manual or contact your dealer's service centre — they can confirm whether your rear window carries an integrated brake light. If you see a separate brake-light cluster mounted to the bodywork instead, your vehicle does not have this feature.
Replacement impact
The replacement rear window must carry the identical integrated brake-light pattern so the original lighting circuit reconnects without modification. The conductive elements — whether silkscreen, wiring, or bracket fittings — must align precisely with the vehicle's electrical connections. Using a standard rear window without this pattern would disable the brake light. We source the correct OE-specification glass to ensure a seamless fit and restore full functionality.
GPS1
2006–2007On the Mercedes M Class: fitted on 1 of the 4 rear window variants we list (25%); model years 2006–2007.
GPS antenna built into the windscreen connects your sat-nav to satellite signals for reliable navigation.
What it means
A GPS antenna is laminated into the windscreen glass during manufacture, providing a direct aerial connection for your vehicle's satellite-navigation system. This integrated design offers better signal reception than external antennas and a cleaner aesthetic. The antenna print and electrical connector are engineered into the glass itself, allowing the navigation receiver to lock onto GPS satellites without interference from the vehicle's metal body or other components.
How to tell
Check your vehicle's handbook or ask your dealership service centre whether your windscreen carries an integrated GPS antenna. You won't see obvious external aerials or connectors on the glass itself — the antenna is laminated internally. If your sat-nav works reliably without a visible roof-mounted antenna, it's likely GPS-equipped.
Replacement impact
Replacement windscreens with GPS antennas must be sourced as OEM (original-equipment) glass to preserve navigation functionality. The antenna print pattern and electrical connector are specific to your vehicle's sat-nav system. Aftermarket glass without the antenna print will not support GPS reception. We confirm OEM availability when you book; lead times may be slightly longer than standard glass.
Green1
1998–2026On the Mercedes M Class: fitted on 1 of the 4 rear window variants we list (25%); model years 1998–2026.
What it means
A subtle green tint in the glass that reduces solar heat and glare — visible only under close inspection.
On your Mercedes M Class
Factory-standard on many modern M-Class models; your specialist will match this tint on replacement.
Solar Control1
1998–2026On the Mercedes M Class: fitted on 1 of the 4 rear window variants we list (25%); model years 1998–2026.
What it means
The rear glass is coated to absorb the sun's infrared rays, reducing cabin heat and improving cooling efficiency.
On your Mercedes M Class
Offered as part of premium trim or climate-control packages on newer M-Class models; confirmed at the quote stage.
About the Mercedes M Class
The Mercedes M-Class has been in production since 1998, evolving through multiple generations with significant glass and technology updates. Early models carry straightforward toughened rear windows, while later variants from the early 2010s onwards feature integrated antennas, alarm wiring, and advanced tint options tailored to the platform.
Modern M-Class models may include privacy-tint rear glass and solar-control options depending on trim level. Replacement glass is matched to your exact factory specification — whether that's an antenna-integrated heated panel, privacy tint, or standard clear glass — ensuring all factory circuits reconnect cleanly on fitting.
