There is no doubt that there would be a lot more birds hanging around the GA scene if there were a lot more flashy planes around. A TB20 (one in good nick) certainly draws the appropriate attention
I do think single door planes are a bit of an acquired taste though. After 6 years of the TB20, I would never go back to a single door design. 2 doors are so much nicer for me, the passengers, and general usability. As just a little example, much of the time it is windy and cold at the airport and I can get any passengers inside the plane where its' nice and warm while I do the preflight outside, and I can then get in without anybody having to get out.
Obviously the bigger hulls like the Meridian are easier but they have the large back door entry anyway, with steps.
