In 1978, Swiss designer Franco Sbarro created a mobile office based on a Cadillac Eldorado for Saudi businessman Joseph E. Adjadj. The vehicle, over seven meters long and weighing nearly three tons, featured four large seats, desks, telephones, a refrigerator, a coffee maker, and a TV, but no beds or kitchen. The project remained a single prototype, as it was considered too large, expensive, and ahead of its time for an era without remote work culture.
