Those coachbuilt bodies were mostly furnished by Touring in Italy and Saoutchik in France. A few were by Serra of Pegaso's home town, Barcelona.
Touring and Serra bodies stayed close to basic styles of each firm, whereas Saoutchik bodies were more varied.
1952 Pegaso Z-102 Spider "Tibidabo" by Touring
Early on, Touring established its theme of chopped out hood segments. The same was applied on rear ends of coupes. Note the lack of a front bumper. This was fairly typical of Pegasos, though some had sketchy bumper segments up front.
1953 Pegaso Z-102 "Thrill" showcar by Touring
The front end is typical Touring-Pegaso, but the rest is showcar jazz. Some later American Motors designs had a similar feeling.
1954 Pegaso Z-102 Berlinetta by Touring - RM Sotheby's auction photo
This is a typical Touring body.

The greenhouse is high, the hood long: another fine Touring design.
Another Sotheby's photo. Note the chopped-out bits at the rear. The window design is logical, but the chrome links aren't really needed.
1952 Pegaso Z-102 Berlinetta by Soutchik
Saoutchik made a few coupés and cabriolets with this fender design. Unusually, there is a substantial front bumper that some later Saoutchik Pegasos lacked.

This seems to be a more common Saoutchik design for Pegaso. Note the nearly invisible bumper.
The fenderline is thrusting and the greenhouse is small.
A more squared-off trunk lid blended with the fenders might have been more practical and better looking.

The lower body design is the same as that of the car in the previous images.
Rear bumpers offer no serious protection. This car should never be parked on a Paris street.
1955 Pegaso Z-103 Spider by Serra - unknown source
A nice, clean design. Unlike most Pegasos, this car and the one below had panoramic (wraparound) windshields: very mid-1950s.
1956 Pegaso Z-102 Spider by Serra - unknown source
This car has a fairly serious rear bumper. I like this rear design better than Saoutchhik's. It's bold, but logical. Note the vent on the front fender that's absent in the car in the previous photo.
