The back seat should be reserved for people under 5' 10", though. The rear doors open to a middling amount of knee room, and the seats themselves could be a little less firm. The standard sunroof pushes the headliner down deeply into passenger head room, and there's no "delete" option on the order sheet.
Cargo space, on the other hand, is good, with an ample trunk and plenty of in-cabin pockets and compartments. The Sport Wagon is a winner, in terms of usability, even though the cargo area of 25.8 cubic feet of cargo space seems a little shallow. It will accept a few roll-on suitcases, or Costco boxes, or at least a couple of iMac boxes stacked flat. There's also a bin under the cargo floor for secure storage. It's far roomier than the larger, heavier, less useful and mostly ridiculous Acura ZDX crossover.
While the comfort and quality of the TSX are just shy of top-notch, they're right on par for the mid-size luxury sedan segment. Acura's selection of materials is high, and fit and finish are one of the best reasons to recommend the TSX.
