Duncan Brown thinks those long-gone dealerships need a little credit as well, and has given you the full story on almost 20 of them in this “Must Read,” “Lost Muscle Car Dealerships.” Whether through backdoor deals with GM or custom work in their own performance shops, all of these dealers were responsible for putting some serious horsepower on the street. Better yet, Duncan also hit the road all across the country to photograph what these dealerships look like now, or take pictures of whatever condos or strip malls currently occupy these hallowed grounds of muscle car history.
