The GL8 trunk can accommodate at least two 28-inch suitcases. The Buick GL8 has a spacious trunk, and fitting three 28-inch suitcases is also not a problem. Below is relevant information: 1. GL8 trunk dimensions: Without folding down the rear seats, the older GL8 model has a trunk height of 1200 mm, width of 1250 mm, and depth of 615 mm. If the rear seats are folded down, the depth increases to 1500 mm, making the trunk space very large. 2. GL8 interior: The interior continues with Buick's wraparound design language, combining both quality and a sense of technology. The new model builds on features such as HD streaming media rearview mirror, HD 360° panoramic imaging, SBZA side blind zone warning system, and APA automatic parking, adding intelligent driving assistance configurations like ACC adaptive cruise control, LKA lane keeping, LDW lane departure warning, FDI front distance indication, FCA forward collision warning, and CMB collision mitigation system, further enhancing safety.

My GL8 has been with us for over three years, and it's been our go-to for family trips. With the third row up, you can fit two 28-inch suitcases in the trunk if you place them vertically against the sides—they stay pretty stable. If you need more space, folding down the third row lets you fit four or five large suitcases without a problem. But when I take my family out, we usually go with two suitcases and a few backpacks, leaving some room for souvenirs we pick up along the way. The thickness of the suitcases matters too—if they're too thick, they might press against the trunk lid when placed vertically, so stacking them sideways in two layers can save more space. For airport pickups, the most I've packed was three suitcases plus two golf bags.

It's common to use the GL8 for client pickups, and I'm well aware of its trunk capacity. For large items like 28-inch suitcases, you can fit a maximum of two without folding the seats, preferably placed vertically against the rear door. If you fold down the third-row seats, the entire floor becomes a flat surface, and in practice, you can fit four suitcases with an additional carry-on stacked on top. Just remember to remove the cargo cover beforehand, or it will press down on the luggage. Actual usage depends on the suitcase design—those with protruding wheels take up more space, and hard-shell cases are harder to fit than soft bags. I usually recommend clients prioritize folding the middle seats to maintain rearview mirror visibility.

Last week, I drove the GL8 to the airport to pick up relatives and managed to fit four 28-inch suitcases in the trunk. The trick is to completely flatten the third-row seats and arrange the suitcases vertically—two in the front and two in the back—with backpacks stuffed in the gaps in between. Without folding the seats, you can fit two suitcases snugly in their normal state; any more would require stacking them on top of each other, pressing against the cover panel. Pay attention to the direction of the suitcase wheels—aligning them with the grooves saves more space. For regular grocery runs, it easily holds over a dozen shopping bags, and during the New Year, the back seat can accommodate three crates of fruit for hauling holiday goods. The actual cargo capacity is more than double that of a sedan.
