CHRYSLER "72" PHAETON

(Seven-Seater)

Down to the smallest detall, this roomy, powerful, stylish Phaeton (with custom body) is an example of the Chrysler engineering genius at its full flower. Everything that the most exacting motor- ist could demand is found in this Phaeton as a matter of course. Flectness-72 and more untiring miles an hour. Acceleration-a flashing surge that puts you at the head of all traffic. Endurance- a thousand miles is merely an incident in the life of one of these staunchly-built Phaetons Proud owners are still at the' wheels of their original Chryslers, bidle four years ago—many of them with more than one hundred thousand miles on the speedometer, The "72" seven-seater Phaeton accommodates five adult pas *sengers in the rear compartment and two in its ample front seat, with room to spare. Folding auxiliary seats are wide and restful, and so placed as to allow unhampered leg-room for the occupants of the wellsprung rear seat.

Harmoniously blended colours, snugly folding hood with bind.`· ings to match the durable, high-grade pigskin leather in which the car is upholstered. A long, low, fleet-appearing body, appar ently small and compact, but seating seven adults la perfect comfort—surely a car you will be pleased and proud to ownl
