While the ES 350's rear end is appealing and tasteful, the profile is rather conservative and featureless, save for out-of-place, aggressive headlamps. Although it's still quite bland on the outside, the 2010 ES 350 gets the equivalent of a 'sharpen,' in photo-editor-speak. A new grille looks a bit larger, with a lot more chrome and a slightly different headlamp design to match, while the front corners have been brought out a bit more. New fog lamps and a wide, thin lower air dam complete the new and slightly different look in front, while the tail lamp design has been modified to suit the front details. Alongside, metallic trim for the side sills bridges the wheel wells, and new wheel designs also help freshen the look.
Cars.com says that the ES 350 has a "classy, conservative design," while also acknowledging the vehicle’s “sharper angles and more defined body panel creases.” Motor Trend agrees, commenting that “from the nose on, the sheet metal flows into a rakish, aerodynamic body with a bit of the GS and IS sport sedans' flavor.” MotherProof describes the exterior of the Lexus ES 350 as "curvy and sharp,” while Kelley Blue Book wonders if it may be "a bit too conservative."
The interior takes a slightly different direction, becoming warmer and softer, yet brighter, though the overall look is also very conservative. Although the 2010 Lexus ES 350 and Toyota Camry utilize the same running gear, Edmunds points out that “the ES doesn't share a single dash panel or material with its less expensive Toyota sibling.” And overall, reviewers are very positive about the interior, even if it's not at all flamboyant. “Inside the ES is a combination of indulgent shapes and textures that are as functional as they are pampering,” says Edmunds. Cars.com reports that the controls “are easy to learn,” while Car and Driver, calling the interior of a previous model-year ES "posh," adds that it “has a flowing dashboard design [that] looks a bit plain when finished in black.” In the opinion of TheCarConnection.com, 2010's sharpen has helped a bit with that.
