The first model of 603 was characterized by three headlamps.
Originally the three headlights were under a single piece of glass, but later three-piece glass was used.
There was a large luggage compartment under the front bonnet, under which was the spare wheel.
The spare wheel was in a separate drop-down bin opened from inside the front boot, thus making it possible to reach it without taking out luggage.
At least one prototype had a two-piece windscreen but production cars had single-sheet 'screens of two different heights and three curvatures during the long production run.
The interior featured enough space to seat six occupants.
To gain enough space for the middle occupant in the front seats the shift lever was on the steering column, rather than on the floor.
The front seats could be folded down to make a large bed.
Behind the rear seats there was a deep storage area, initially covered.
The rear was characterized by a large two piece window making it the first rear-engined Tatra with good rear visibility.

An independent petrol-burning heater is fitted under the front seat.

Low volume production levels and the resulting lack of production automation meant that "one off" adaptations were relatively easy to accomplish.
