I have 5357 (two S/N's later than that one). 5360 is also here in Arizona, highly modified. 5358 is in Europe (Sweden?) with a wild paint scheme.
There is no information in the DeTomaso Registry on 5355. So if you can get pictures of the car, and the identifying data (S/N plate in the window, on the footbox, on the doorjamb, and the data plates in the engine bay, as well as the ZF S/N and engine number (back of the engine, by the left side head), and send them to the Administrator on the DeTomaso Registry, you can get access to the searchable database to evaluate many cars, and find a lot of their history.
Enjoy the shopping!
Here's some of 5355's brothers and sisters.
In order...
