Mile of Cars

Mid-century auto retail strip on National City Boulevard, a relic of post-war Southern California

National City Boulevard, between 18th and 33rd Streets, has been the densest concentration of car dealerships in San Diego County for almost 70 years. The strip is still active — about 20 brands sell side by side — but the more interesting layer is the surviving mid-century architecture: cantilevered glass showrooms, period neon signs, and the giant 1956 entry arch that has become a city landmark.

This is a quintessentially American sight, and one few visitors think to look at. The best time to walk is on a Sunday morning when the dealerships are closed and the lots are quiet — sun bouncing off the polished steel, vintage signage clearer without the bustle.

A story
The Mile of Cars opened in 1956 as the first auto mall in the United States — a coordinated row of dealerships marketed under a single sign — and the model spread across America. The original neon archway at the entrance was restored in 2009 and is one of the few surviving examples of the mid-century 'dealership corridor' typology.
