After its use as a development mule prototype #2 was used as a personal car by team member Colin James, after which it was acquired by Peter Dodds, another member of the Monica team. In 1969 prototype chassis #3, the first to receive a ZF 5-speed manual transmission, was built. At this time the Tastevins introduced Tudor (Tony) Rascanu, a Romanian exile and former shop manager for Vignale in Italy, to the project. Rascanu was entrusted with the job of completely restyling the bodywork for the third prototype, but was not allowed to make any modifications to Lawrence's chassis, which was to be sent to French coach-builder Henri Chapron in Paris. Chapron was to build a full-sized maquette, or body-form, of the revised car under Rascanu's oversight. Rascanu and Capron's work met with Tastevin's approval. With hidden headlamps in a sloping aerodynamic nose and wide horizontal taillights it was much more appealing than the previous two attempts. The maquette was then sent to Carrozzeria Alfredo Vignale in Turin to be used as a base for Vignale to produce a body in steel. Before delivering the maquette to Vignale, Tastevin asked Lawrence to first deliver prototype #2 to the workshops of Virgilio Conrero, also in Turin. The famous Alfa mechanic was to do a detailed assessment of the Martin engine and evaluation of the car's performance. Conrero was critical of almost every aspect of the Martin engine and was skeptical of the power curves provided by Lawrence. He told the factory “this engine is a trap that will never work under normal traffic conditions”. Conrero insisted on a flying-kilometre test of the prototype, after which he would run his 2-litre Giulietta on the same course for comparison. Lawrence suspected that Conrero was trying to discredit both the Martin engine and LawrenceTune in an attempt to take Lawrence's place on the Monica project. He examined the times recorded for the Monica's run and discovered an irregularity in the numbers. When Tastevin confronted Conrero with this information the testing was halted and Conrero's involvement in the project ended. Lawrence delivered chassis #3 to Vignale's carrozzeria, and they completed the body in steel. While prototype #3 was a significant improvement the Tastevins were not yet entirely satisfied with its appearance. Performance of this car was also disappointing due to it being between and overweight. By way of explanation Lawrence drilled a hole into the
