Makes sense to me. In those days, they higher the line, the better the
quality. I'm sure Olds, Buick and Cadillac were built with an oil filter,
recirculating ball steering, and all the good stuff we have come to take
for granted these days. Now, it doesn't make a bit of sense to buy upscale
since all the cars are built to the same low standards.

P.S. Its an engine, engine mounts, and engine oil. Not a motor, motor
mounts and motor oil when referring to primary power sources as in the case
of a gasoline or diesel power plant. Those terms are throwbacks to the
days when grammar school dropouts didn't know the difference. Englighten
people of the 21st Century should use the proper nomenclature.
