The danger with a company that's been liquidated, is if IP you want to license doesn't all belong to the same entity. In the case of Marcos, wiki says some of the physical assets were sold to one company (Marcos Heritage Spares), whilst according to Companies House a second company (Page Motors) recently became Marcos Motor Company Ltd... as it happens, both these companies seem to have recently appointed the same directors.
Yet, a quick trademark search shows, for example, the Marcos logo being registered to a company in the Netherlands for Class 12 (motor vehicles etc.) whilst the same logo is registered to Marcos Sportscars in the UK for Class 9 (electronic games inc. video games). Neither Marcos Sportscars nor Marcos Investments B.v are anything to do with Marcos Motors or Marcos Heritage Spares.
The short version of that, is you could have two separate entities, with a reasonable claim to IP that PD would need.
I wasn't going to spend hours looking into this, so I'm not saying as a fact this is the situation with Marcos, but it should demonstrate some of the issues you could have. A more well known example of how weird things can get when companies change statues, is Rolls-Royce.
