Maxwell
--a car having every luxury
_ _ except one I
HAT luxury is brurrsh oigness, which means weight,
which means a large gasoline tank and filled often,
and large tires, and several sets a year.
Maxwell is neither a big car nor a sin:-.rll car. The big-
gest car made is less than 4 feet longer, and costs around
$15,000 to buy and $7,000 sr year to run. ‘
Most cars are just a foot or 11 few inches longer.
_ l
And others are some smaller -shorter, lighter, lcssroomy, ' ‘
and hence_iacl: the luxury of a Maxwell. -
Nor do they cost, on the average, less to run.
Gas mileage is vtry i°»':nrl.,f the same. Tire mileage is
very nearly the same. _
But where Maxwell earned its crowning reputation has
been its ability to run and run and never quit. ‘
4
That mean s repair bills are amazingly low. _
_You therefore never get mad at a Maxwell 1 it`s the best
friend your pocketbook has. And when you '
stop to think of all those little points of 
luxury in a Maxwell you`i‘c almost sure '  gl
to whip out your check book and write a  :»,i
