Interesting subject. Have thought a bit about this as I have been fortunate enough to put in some quality drive time as well as quality cleaning!
At first I was fantasizing about acquiring the aero screens as well as mirrors to match but then after an almost grueling trip through some bug happy stretches and the inevitable cleanup I killed those thoughts.
The M3W, as is, is a very clean aerodynamic shape which really helps the cleanup. I may get the stainless wire rock guards for the lamps but I am very pleased with what I have!
My other hobby is building and listening to tube/valve powered stereo amplifiers and long ago it became readily apparent to me that other people's opinions don't matter. It has to sound good to me.
I bought the Morgan for me. It will be what I desire it to be.
