International unveiled its new tractor at the Chicago Auto Show with all the pomp and circumstance that new, heart-of-the-market automobiles used to enjoy. The new LoneStar's impressive presence owes much of its charisma to the 1930s-era styling cues of the early C-, and later, D-series International trucks. But the old-school theme stops there. Both Day Cabs and Sleepers sport interiors as modern and inviting as a brand-new den. Over-the-road just became a lot closer to home.
