In all versions, the 2010 Lexus LS has amply large, comfortable front seats, supple and roomy backseats, and a large trunk. The front seats are not as supportive as they could be (Sport versions have somewhat more bolstering), but a very wide center console makes the area feel unexpectedly narrow. ConsumerGuide reports that "front is spacious for adults, though taller drivers may need more headroom." Whether it comes with four seats or five, Car and Driver feels that the seats on the LS are "all-day-comfortable" and make it a "comfortable long-haul cruiser," according to Cars.com.
In back, there's adequate room even for tall and lanky adults in short-wheelbase cars; the L editions afford limousine-like space in the backseat area, thanks to five inches of added length versus the standard LS. Kelley Blue Book says the long-wheelbase versions' longer body "yields vast space for rear-seat occupants." If seating space doesn't impress, consider the ottoman-style seating option with built-in massage features. Edmunds reports "seating and accommodations are as regal as you'd expect in a car of this category, and then some," comparing the seats to "a Shiatsu masseur." Motor Trend confirms this impression: "to get a sense from behind the wheel, imagine sinking into a lavish and serene home-entertainment room, replete with Eames lounge chairs covered in the supplest leather."
Trunk space and interior storage are fairly large, and hybrids have 2 cubic feet more space this year thanks to a recent repackaging of their batteries. That's a mild improvement over the 2009 model; Edmunds says in the '09, "trunk space is a serious issue...hybrid components and the optional rear seat climate control system drop capacity to a middling 11.7 cubic feet (2 cubes less than a Toyota Yaris)." ConsumerGuide finds that "the trunk is sufficient for most travel needs" and "in-cabin small-item storage is good."
As for quality, few vehicles at any price point are assembled with the Lexus LS' tight panel gaps, though other luxury four-doors offer far richer-looking materials. Some of the LS switchgear mimics that used in much cheaper Lexus models, but the same can be true of vehicles from Mercedes, BMW, Jaguar, and Audi, too.
Cars.com claims the LS 460 is "near the top of the luxury sedan pack in terms of material quality." Edmunds agrees, noting that "the fit and finish is without peer" on the Lexus 2010 LS 460. Little touches abound on the LS 460; for example, Motor Trend reports "the steering wheel is buffed for three hours and sewn with ultrasoft stitching." Kelley Blue Book waxes enthusiastic about "acres of creamy aniline cowhide French stitched like a Folies Bergere corset." According to ConsumerGuide, this 2010 Lexus is "one of the quietest cars on the market...the engine is nearly silent at idle and emits a subdued growl under aggressive acceleration...there is virtually no tire, road, or wind noise."
