In the final version of the Moskvich‑3‑5‑7 “Delta” mock‑up, the shape of the door handles was revised and positioned higher. The headlamp washers, the “American‑style” marker lights near the headlights, and the antenna were removed. The fuel filler neck was relocated lower, with its former position now occupied by the “Delta” inscription. Marker lights were added to the rear fenders. To enhance realism, certain elements of the mock‑up were painted, and the “windows” were polished.
