to paraphrase David Richards (team principle of SWRT) "were spending tens of millions of dollars, but not as many tens of millions as Ford or Puegot"
money. that is why subaru has only been running 2 cars. and this is also the first season where you could run 3 cars and have the top two, regardless of who they were, score points. it used to be that you had to nominate 2 drivers and they were the only ones eligible to score points, even if another driver finished higher.
remember, SWRT has been without a major sponsor since '98 (until this year). they just havn't been able to afford a fleet of cars and drivers and crews.
