This is primarily driven by the absolute quality of the products the company produce - the 911 is so good that (for me) it fails to impress as a weekend/fun car and instead falls into the daily driver camp. Even the 911 Turbo, which was once a lairy beast (up until, and including, the 964 Turbo 3.6), has become a car that anyone car drive at 9/10ths and get away with almost physic bending lack of fineness and skill.
Just catching up on some of the threads and this for me Simon, your post is definitely nail and head. I love our 911 as a daily driver, it is ruthlessly focused and mechanically perfect (so far), but definitely not special enough to be a weekend fun car imho. It has no soul, does that mean faults.........as the AeroMax has soul in abundance, but is also blessed with one or two, let me call them Morgan procilivities!
