I don't see the rear seat headrests as something to complain about since they are removable.
I am 6'3'' and I too wish for better seat support. And a telescoping steering wheel since I have the seat back all the way to get a little legroom. Shorter drivers probably don't need this.
The driver side sun visor hits the rear-view mirror when pushing it forward. WTF??? Plus it could use a built-in extension, like my Tundra has. Maybe an aftermarket extension is available? I also like the thin 2nd visor on the Tundra so I can have protection from the sun front and side when driving on winding roads. How much can this cost to add?
I think the headlights are not good enough for night driving. I plan on looking into aftermarket lights.
I wish anti-lock brakes were standard although I know they are an option.
I am one of those full-size spare tire in all cars zealots. But at least a full-size spare does fit in the trunk so I did buy one. At least they made the tire well big enough to allow for this upgrade.
I agree with the comments about needing better OEM tires.
Someone remarked about disappointing gas mileage. My gas mileage ('05 LE, now with 3200 miles) has been great. On a recent vacation of over 2400 miles, I filled up 7 times and topped 40 mpg on 5 of them. Two drives were mostly in the mountains and one of those was 35 mpg and the other was 39. I'm very satisfied with this feature of my car. For those who like numbers, here are all of my mpg figures since buying the car - 37.5, 37.2, 42.5, 40.1, 41.1, 41.4, 35.1, 38.8, 41.0.
