If I were you, I'd take a trip to Lake Geneva, WI to inspect and drive it. The 23rd Series Super Deluxe Eight has the looks and feel of the Custom Eight without the extra expense, easier to live with and enjoy.
If this car is as good as or better than it looks in the poor photos, and mechanically robust, it would be a great bargain. That 327 is one sweet engine!
