This a very solid feeling and quiet running car. There was no cowl shake as others reported. I own two LS 400-430 cars and this car is as solid and nearly as quiet as these are. The visibility with the boot top in place was only fair but without the boot-top installed visibility was adequate!
Fast opening top. Automatic window opening when lowering top. Seat heaters on cool mornings.
Modify boot top to improve view. Power passenger seat. Brighter backlights on the upper three console instruments. (Which can't be seen in sunlight with top down.)
