Same issue with my Unique. I hold the nozzle high in the filler neck and aim sideways a bit so it corresponds to the bend in the tube. Still have to go a bit slowly though. A filler line vent would help, but what's the rush?
Filling the Cobra is always a spectator event complete with fans, hecklers and commentary. We have no self-serve stations down here, but the attendants always cheerfully let me do my own filling. Just one more little quirk to add to the experience.
I always have a towel or two in the trunk, but mostly for wiping up after unexpected rain showers. I don't think I'd want to put a towel back into my trunk with even a little bit of gas spilled on it. The times I have had some fuel puke back onto the paint, I just splash it down with some soapy water from the glass cleaner trough after filling up and I've never seen any damage to the paint.
