One advantage of Avgas that we need to consider is its resistence to vapor locking if you own an L-71 or a Rochester FI car, this might be important to you.

This appears to have some validity, some owners have found that a simple change to non-ethanol gas does the trick. Others have found that either a given car is 'immune' to vapour lock irrespective of what type of fuel is used or that their local blend of E10 is no more subject to vapour pressure issues than pure gas.

Rich,
Good observation, av-gas does not vapourize as moch as auto gas for an obvious reason.

On the other hand when they approved auto gas in some aircraft there was a service bullitin that either limited or warned about the auto gas vapour problems at higher altitudes.

10K seems to ring a bell

I have had a complete reversal in fuel use for years. I can get av-gas easily and cheap. I use a blend of av-gas in the high compression cars I have and a blend of auto gas in airplanes. I put auto gas in one wing, av-gas in another and depending on the temp I can use one or the other and blend selecting both tanks.
