I think Volvo still has to give their permission for a race team to use their cars? I dunno.
But what sane race team would use a Volvo for their car anyways without Volvo sponshorship/backing when you can run Porsches or Mustangs or something that's easy to make fast lol...
I believe it depends on which series you're talking about. In the DTM, you do need the manufacturer permission. In the WTCC, I don't believe you need manufacturer permission. Volvo still races a manufacturer backed S60 in the STCC. I believe an independent team also races a S60 in Danish Touring car series.
