While the GL may look sleeker than its competitors, Mercedes brags that the 2007 GL 450 offers both best-in-class interior room as well as ease of entry and exit.With all seats in their upright position, there's still 14 cubic feet of storage between the third-row seatbacks and the closed rear hatch door. A power folding feature for the third row is standard equipment on the GL with controls near the rear hatch and next to the right-side second-row passenger's seat. Power down those third-row seats, and cargo capacity expands to 43.8 cubic feet. Fold down the 60/40-split second row seats and the GL provides as much as 83.3 cubic feet for cargo. There's also room under the cargo floor for a full-size spare tire.
Standard equipment includes eight-way power front seats, 14 air conditioning outlet vents, eight cup holders, air vents, and reading lamps.
The interior layout is familiar to Mercedes drivers, with either faux or real leather trim for the seats (Mercedes notes that not all luxury car buyers want real leather seating surfaces), wood trim and metal rings around gauges, air vents, and cup holders.
The second-row seats provide ample legroom. When occupied by only two people, the back of the center section can be folded down as an armrest and storage tray.
