A lot of us have the V35. Just use a Carenado livery and pretty good chance they’ll see you. The custom registration is always just a blank panel though to prevent unsavory things written on aircraft.
It doesn’t make sense at first with non custom permanent registrations that don’t match your personal one, but in group/formation/MP photo flights those with the same livery won’t see giant rectangles on your aircraft.
The c414, c310, and BS baron mod kind of stole the Seneca’s thunder, but it was popular for a little while .
