Cargo & Trunk Liners — Price Comparison

Cargo & Trunk Liners for 2012 BMW M3

A cargo liner does for the trunk of a 2012 BMW M3 what floor liners do up front: contains the mud, spills, and pet hair that otherwise grind into carpet you can't easily replace. Molded trays with raised edges hold liquids; flat mats just delay the inevitable.

We compared 3 offers across major retailers for the E90 platform (2008–2013 E90). Prices range from $59.99 to $129.99 as of the last update.

Best picks

• Best overall: A laser-measured molded liner with a raised perimeter lip — wet gear and grocery spills stay on the tray instead of soaking into the carpet.
• Best budget: A heavy universal trunk mat trimmed to fit. No lip containment, but it stops the everyday abrasion that wears through factory carpet.

What to look for

• Seat configuration affects liner shape — liners differ for vehicles with third rows folded vs removed.
• Subwoofer or cargo-area accessories can interfere with full-coverage liners; check the cutout pattern.
• If you haul dogs, look for liners that pair with a matching seat-back protector.

Enthusiast platform note: this chassis has a deep aftermarket, so OEM-replacement parts listed here sit alongside dedicated performance lines. If you're modifying rather than maintaining, check the brand's motorsport catalog for upgraded versions of the same part.
