It all looks great but when you start feeling around and touching the surfaces many of which will squeak or move at that touch, you start to understand they did a masterful job of making it appear of a higher quality than the reality.

It's definitely a temperature sensitive issue...seems like when the seat is warm/hot from the car being in the sun, the seat creaking is very pronounced. If the car was in the garage or in the evening, the seat creaking is hardly noticeable.
