Thanks for such a great site; I think you'll appreciate the family suburban.
EVERY single tank of gas ever put into this 1972 GMC has been recorded in its log books. The logs typically record Odometer, price per gal, # of gallons,octane and date. Other pertinent data about the fill up is often included too. Given the meticulousness of the data records, you can just imagine the maintenance and care level given.
This suburban is primarily a "terra-plane" for cross country family trips; and getting into it is just like going back to the 1970's (with the exception of a 1980's tape deck). If anyone knows of better documented burb, please let me know.
Here are some pics.
