I don't know if its something simple like the angle of the pedals or column are slightly different or perhaps the seating ?
Although picky the only thing I don't like about the Saxo interior is the radio fitting is not quite right, the bottom of it pokes out almost like its not designed to go in there (factory unit) or the angle of the hole is wrong. There are some sensible things too such as a temp gauge on the later models (can be forced into a 106 with a sensor change and a tweak at the panel multiplug)
RHD's only, those having tried a LHD 106 would of found a much superior driving position (compared to RHD, at least I found it so) without pedals and a better design of them without being at an odd offset too.
