for a team that doesnt want to spend much money they have been on a massive recruitment drive recently.Besides even without a spending agreement it won't matter to mercedes because they are reportedly not all that interested in spending much more than they get back in installments from mclaren. Plenty of reports suggesting Mercedes are not all that interested in listening to Brawn and suits not all that happy with what they are already spending at the team.
Dieter Zetsche is the only suit at mercedes that matters and he understands how importaint formula one is, anytime merc get a good finish hes on the phone to the drivers and haug straight after the race
