Inside, the Corolla is well designed and reasonably comfortable, although the stark, basic feel is going to be a turnoff even for discerning shoppers on a budget.
Base L, LE, and S trims are offered, and in the latter two the Corolla gets a little more dressed-up; but even then the conservative design and subpar materials conspire to give this sedan an on-a-budget feel and not much more.
But there are plenty of positives for the Corolla, if seating space and comfort are what matters most. Ride comfort is good in most cases, and the Corolla's cabin is well-isolated from road and wind noise; it's really up to par with mid-size cars in this respect. Seating in the Corolla is quite good overall, with plenty of headroom and legroom in front, and even decent space for average-sized adults in the back seat. But front seats are a bit short and spongy; they're not so comfortable for longer trips.
Storage-wise, there's a double glovebox, along with a few cubbies, a console box, and large door pockets, but the trunk is on the small side, even among cars in this class, and has intrusive hinges.
Powertrain refinement used to be a Corolla strength, say a decade ago, but the current model sounds coarse when pushed, considering today's higher standards of small-car refinement.
