For those of you that have a Genesis in the new Sapphire Blue color, do you find that it is difficult or requires more effort to keep it clean, sort of like a black car? I've been leaning toward the Titanium Gray, except that it is not available in the cashmere interior. I'm concerned that the black interior would be too hot in summer, and I just haven't been able to warm up to the saddle interior based on photos. Thanks in advance for your thoughts.
