Mar.20 (GMM) The first race of the 2013 season came and went without Marussia signing a commercial agreement with the sport's owners.
In the days before Melbourne, team boss John Booth denied Bernie Ecclestone's recent claim that the F1 chief executive had agreed a new deal with the Banbury-based backmarkers.
"It's vital for Bernie because he won't be able to film us without it," Booth had said.
"It does seem a little strange to treat one team so differently, but then again I don't work for CVC so I assume they have some reason for this," he said.
"The real question is: why us? We would argue we're a pretty good team and we're making good strides."
Lowdon claims that if the situation continues, sponsors may be deterred from backing Marussia.
"The other teams have an agreement (so that) will come into discussions with sponsors," he said.
"It unsettles them that we should be treated differently to other teams. There is a knock-on effect, there is no question."
