I sat in my first f10 5 series yesterday at a local dealer. Initial impression was leather work and stitiching is better than e60 and more Audi-like. I was extremely unimpressed with plastics used on vents, ashtray, and seats--they seem to "glossier" much like cheap plastics you see in American cars. The vents do not have the solid feel of the e60 but are thinner and flimsier. Im sure it was weight savings but even the ash tray did not feel up to the previous quality I am used to. I have been very pleased with the quality of leather work and interior in my 2010 m6 and will likely move to f10 m5 at some point. I hope im wrong in my view.
