[9] Both companies have agreed to explore collaboration opportunities in the areas of technology enhancement, new product line up and the sharing of vehicle platforms and facilities.

[13] On 7 November 2013, spyshots revealed that the PRM would indeed be based on the North American eighth generation Honda Accord.

[14] It is not known whether the PRM would be exported to other countries, although such plans are highly unlikely judging from the Proton Inspira's marketing strategy.

Additionally, three bespoke long-wheelbase editions have been produced for the sixth Prime Minister of Malaysia, Najib Razak, Muhyiddin Yassin and the Prime Minister of Turkey, Recep Tayyip Erdoğan, the latter of which is a left-hand drive unit and a celebratory gift in view of the 50th anniversary of Malaysia–Turkey relations.

[16][20] Only two long-wheelbase editions have been produced for exclusive use by the sixth Prime Minister of Malaysia, Najib Razak, Muhyiddin Yassin.

Additionally, Turkey has historically been a strong market for Proton, and the company plans to introduce the new Prevé and Suprima S models in the country by 2014.

[24] Mahathir Mohamad, the chairman of Proton, has made mention that an unnamed aircraft company with the capacity to design cars has also been enlisted in the P4-90B's development.

[25] It was reported that Mahathir had exported his personal Perdana to the UK to contribute to R&D efforts to create an electric vehicle.

[26] A heavily major makeover of the Perdana's exterior based on the eighth generation Accord was launched in Malaysian market on 14 June 2016.

[29] On July 15, 2016, it was suggested by the Argentine ambassador to Malaysia that Proton may have a good market audience if the Perdana is exported to Argentina.
