After driving the Optima for five days straight for 10+ hours per day, other than the occasional stop, on a road trip, not one time did I get a sore back or thighs. see full Kia Optima review |
What Our Members Are Saying about the Seat Room and Comfort of the 2007 Mazda RX-8
| 2007 Mazda RX-8 Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2007 | 4dr Coupe 212-horsepower 1.3L R2 6-speed shiftable automatic RWD |
Excellent for long trips. Even though I suffer from spinal stenosis, I did a two-day 1800 mile trip with no troubles and felt great on arrival. Most modern cars have comfortable seats, but these also make me feel like I am part of the car. see full Mazda RX-8 review |
| 2006 | 4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD |
Rear seats are functional for adults, which is unique for a sports car. see full Mazda RX-8 review |
