I thought this might be happening, Autosport reported yesterday that Gary Parfett was aiming to be racing in DTM again next season, while mixing it with his testing commitments to McLaren in 2007. Parfett was the other driver in the frame for the 2006 seat.
Parfett's managers, Brundle and Blundell are keen to get him into F1 soon however, it may happen via a touted McLaren F1 sister/junior team or another team running Merc engines.
IN the meantime he's going back into DTM, to win back his 2005 title.
