New Magic-Mirror finishes! Literally, the, '59 Buicks are new and wonderful from road to roof ... a new generation of great Buicks!
LESABRE – THE THRIFTIEST Buick
You'd never guess from the looks, inside and out, that the '59 Buick LeSabre models are the thriftiest '59 Buicks. In fact, from the low, luxurious appearance of its styling ... the unique new over-hanging rear roof and Vista-Panoramic windshield, one might think that the LeSabre four-door hardtop, shown below, was one of the costliest cars on the road. The truth is it's far from it ... and certainly within reach of 'most every new car buyer.
INVICTA – THE MOST SPIRITED Buick
If you're the kind of a person who likes high-stepping action ... then one of the fabulous '59 Buick Invicta models is the right car for you. For with just a touch of the accelerator Buick's new high-performing Wildcat 445 engine and fluid-smooth Twin Turbine transmission (both are standard equipment on all Invictas) whisk you out ahead with barely a whisper of effort. Try the Invicta two-door hardtop... and see what fun driving can really be!
ELECTRA – THE MOST LUXURIOUS Buick
Once in a decade or so a new car is introduced that is exceptional in every respect ... an automobile that makes an indelible mark in motoring history. This is the case with the 1959 Buick Electra. For here, as illustrated in the Electra 225 four-door hardtop, are the rare qualities that make a motor car truly great ... simplicity and purity of design, sound and creative engineering ... with careful and exact manufacturing. This is Buick Electra for 1959.
