On the other side of the ledger, here in New Zealand, there were

hundreds of Super Sixes from 1916 thru 1929 which were modified to use

as Service Cars (extended chassis, and up to 16 seat bodies). Most of

these did hundreds of thousands of miles under severe condition, and

none of them had the engines modified. My own '29 Hudson 7 Pass. was

in daily use from 1929 thru 1952, averaging 250 miles per day, which

adds up to over 1 million miles. The cylinders had been sleeved back

to standard after 3 rebores, but the crankshaft was still standard,

though extremely worn. The valve guides were worn out, and the seats

had inserts but the auxilary drive was also unworn except for the

portion of the shaft where the pump seals had been tightened. All the

spring leaves were worn half way through, and the shackle pins stepped.

Rear axles broke, but the engines very rarely failed.
