Reviewers have different opinions about the room and comfort of the 2008 Mazda MX-5 Miata, and few mentioned its build quality.
Jalopnik says the 2008 Mazda MX-5 Miata is "anything but practical," while ConsumerGuide says it has "surprising practicality." Perhaps it’s a matter of differently sized drivers; as Consumer Guide points out, "those over 6-feet tall may want more legroom," and "those under 5-foot-6 may have trouble seeing over the high dashboard." Mazda did try to remedy this issue; Cars.com notes that with the Miata, Mazda has added a new driver's side seat height adjustment, allowing shorter drivers to achieve maximum vision and comfort.
“Because there's no backseat, the two occupants get more legroom than you might expect,” Cars.com observes. There’s a little more room for the driver; the "driver's-side foot well has been widened by running the exhaust down the right side of the transmission tunnel," Kelley Blue Book notes. Still the Miata isn’t overflowing with extra space. “The cockpit is wider than the prior generation's and has greater hip room, shoulder room and elbowroom,” Cars.com says, “but the difference isn't as great as we'd hoped when Mazda set out to redo this model.” As with any sexy two-seater, Kelley Blue Book points out, "If this is going to be your only mode of transport, you're not going to win many friends when it's your turn to drive the co-workers to lunch."
Not only is there not a whole lot of room for passengers in the 2008 Mazda Miata, but the trunk is rather small, and there isn't much in the way of storage space. When the hardtop is retracted and folded away, the Miata has 5.3 cubic feet of trunk space--more than enough for the typical overnight bag, but not an excess of room.
Car and Driver also notes “tire roar can still be tiring on long drives."
