There will be a million automobile replacements in 1921—a million new cars needed to replace old cars. This is because an automobile is one of those things which, when people set their hearts on getting it, they get 1#. To thousands and thousands of people ‘‘more money’’ means ‘“‘new car.”’ In many cases the choice of the car bought will be de- termined by the power of the car and the stability of its manufacturers. The Standard Eight is made by the Standard Steel Car Company of Pittsburgh. This company has the resources, the equipment and the knowledge to make the Standard Eight a powerful car, and to continué making it, so long as roads and highways are used by people in getting from place to place.

And just as it embodies the talent of specialists who are unsurpassed in their particular field, so every other feature has the demonstrated excellence of quality. Delco, Timken, Rayfield, Spicer, Exide, s.Brown-Lipe, Fedders, Borg & Beck—these are the exceptional units of specialists whose work no single plant, however great, could equal. Their selection by Moon engineers is backed by an experienced judgment of fifteen years. The record of Mloonaccom- plishment in engineering w.nd coach work is shown in this wonderful new car where one or two features do not dom- inate at the sacrifice of others, but where every unit gives evidence of thorough- bred quality.

A L O O A TR RN ERAFEEMEAL RSO nOT) RICE appeal has always had its following. But it is truer- today than ever that nothing can substitute for qualily. The winning of the Pike’s Peak Hill-Climb, a phenomenal feat of power, endurance, and efficiency, demonstrated what every owner of a Lexington Thorobred already knows. The fact that the lines of the Thorobred are being copied is the highest form of com- pliment. An almost unbelievable increase in econo- my, power, and all-around performance is produced by the Lexi-gasifier and the Moore Multiple Exhaust System, cxclusive with Lexington. A Other features that place the Thorobred in the forefront of fine cars are the Unified Non- AN SIX rattle Frame, with 100 less parts; the 2 Way Head Lamps, that give full light without glare; the Equalizing Cable-(foot)-brake; and the One-finger Emergency Brak.. Its rare beauty, its maximum of comfort, and the effortless way it scems to skim over the roads are attributes of the Thorobred that beggar description! It is built for those who want lasting qual- ity and who have no patience with mediocrity. In fact, it is a masterpiece of the ten great factories, affiliated with Lexington, that make possible a co-ordination of resources and facilities: the only way, in fact, that such a remarkable car can be built.
