Take even a quick look at the interior of the 2013 Lexus IS 250 and IS 350 and you'll agree that these are luxury sedans, with leather upholstery, top-notch materials, and a long list of standard features, even in base versions. However a cramped interior and more interior noise than other Lexus models can limit these models' appeal.
Front seats are well contoured and firmly padded, but the footwells are narrower than in other sport sedans this size. Rear backseat space is surprisingly tight, with nearly no legroom available when front seats are scooted back for taller drivers; pair that with the IS's relatively narrow cabin, plus tight headroom, and there's really no usable space for adults back there. The trunk is adequate but hardly spacious, at about 13 cubic feet.
While the IS 250 and IS 350 appeal to your luxury senses at first look, they're more premium-grade than opulent--and even with the optional wood trim packages, the IS family feels at times too much like the dressed-up version of a less-expensive car inside.
As with most compact sport sedans in this class, there's quite a bit of tire thrum and road coarseness.
The IS C convertible models, compared to other convertibles in this class, actually stand are among the more spacious and practical, however. The rear seatbacks are a little more upright in back, but thanks to a slimmer front seatback there's enough space for two normal-size adults--for a short stint. Although the tall, wide side sills and rather tall doors and roll hoops in the convertible could leave you feeling a little too pinned-in.
We've also noticed that IS C models are surprisingly quiet and refined--relative to other hardtop convertibles, that is.
