In my opinion, the Mercedes-Benz GL450 is a great looking SUV inside and out, and one of the most appealing models in the Mercedes lineup. However, several exterior cues are derivative. Check out that C-pillar shape, which screams Jeep Grand Cherokee. When parked next to a Toyota 4Runner I noticed close resemblances in the headlights, taillights, and rear bumper design. Inside, tasteful two-tone décor with burl walnut wood trim, silver metallic accents and cleaned-up ergonomics are the rule, and I especially like the padded support bars that span between the dash and the center storage bin on both sides of the illuminated cupholders.
