It's always interesting to look out for what isn't said in interviews: Christian, Max and Pierre all say the Livery is nice (even if one off), and the car looks good. They all mention that the engine is Honda, of course, but they don't mention its nice or good or drivable or whatever - yes its a shakedown so its not the forum for that, but it's interesting, as they will have been briefed on what to say and what key points to mention, hence they all say Livery is great - its a one off - engine is Honda.
Max actually did expand on the experience of driving it: "it felt pretty normal again, of course we've been out of the car for a few months" and a bit later "not proper tires". Not sure what to make of that other than again cold and wrong venue for performance.
Backing up the wrong venue statement earlier - Christian also expanded that it's a cold UK winter day and Silverstone so therefore not conditions that would be meaningful for testing. It's for testing fundamentals, all of which he was pleased about.
Anyway it just struck me as interesting when listening to the interviews... make of it what you will
