Man, you posted exactly what's been on my mind ever since I saw the "yellow" Phoenix Yellow of the E46 M3. Beautiful car but I wish, and still hoping, that BMW will come to there senses and have a deeper more vibrant yellow as an option. Looking at the PY M3 alone isn't too bad but next to Spa Yellow NSX...looks a little puke green tint. But then again, a Spa Yellow treatment to the M3 may not end up like what I'd like to think it would end up as.
