The 2008 Subaru Legacy leans toward the compact end of the mid-size spectrum, though its materials are first rate.
The Washington Post reports "there is seating for five people" aboard the Legacy, and ConsumerGuide points out "plenty of legroom, but headroom is tight for taller riders"--an impression confirmed at Motor Trend, which weighs in with "poor rear-seat headroom." Edmunds says “the backseat is a lowlight, however -- while it's comfortable enough for two average-sized passengers, leg- and shoulder room are unusually tight compared with other midsize sedans.” On the other hand, Kelley Blue Book contends "most backseat passengers should find the Legacy plenty accommodating for trips across town and beyond."
The Washington Post reports that 2008 Subaru "luggage capacity is a smallish (for a midsize sedan) 11.4 cubic feet." ConsumerGuide acknowledges that 2008 Subaru Legacy "sedans have a wide trunk opening and low liftover. The hinges are shrouded to avoid cargo damage, but they take up some space. Standard 60/40 split rear seatbacks fold almost flat." Edmunds confirms this: “The Legacy's trunk is similarly undersized at 11.4 cubic feet, though a ski pass-through and fold-down rear seats help make the most of the car's hauling capacity.”
Cars.com notes that most Subaru 2008 updates "are related to new equipment...the steering wheel has 16 buttons -- a tricky layout where a wrong move could inadvertently remap the accelerator's response or downshift the transmission." ConsumerGuide says "assembly quality has been good on models tested," but "despite a revamped interior, materials are nothing special." However, Edmunds proclaims Subaru 2008 interior materials are "excellent, and style, fit and finish are competitive with more expensive European marques."
Finally, ConsumerGuide reports "the turbocharged engine is subdued and refined," though "some testers complain of body drumming over broken pavement," and "a fair amount of wind and tire noise filters into the cabin at highway speeds."
