The golden age of motoring is rolling into the spotlight. The Heritage Invitational at Ten Tenths Motor Club will showcase four extraordinary pre-war automobiles that exemplify the ingenuity, craftsmanship and performance that defined the earliest era of automotive excellence in this year’s “Grand Classics” class. Among the more than 100 concours-caliber vehicles on display ranging from supercars to Japanese racing machines, a class of early 20th-century classics will pay tribute to the history of the automobile.
