Blue Book cannot add the value of "spirit-directed"* into their calculations. These cars have served the Almighty and will breakdown maybe 15%** less than the exact same car used by a businessperson. Besides, the money is going to Jehovah's organization, so it helps you buy your way into paradise.***
*"Spirit-directed" is just a slogan, no liability for whether or not any supernatural forces aid or hinder the automobile or it's passengers.
**15% less breakdown (or any percentage) is not guaranteed. Subject to exaggeration.
***That is an ongoing promise and never guaranteed.
