to answer fire storm no Evernham Motorsports wont make the switch to toyota! nascar has banned toyota from adding anymore teams to there manufacture!

Could be all of them because if NASCAR doesn't lift ban and if business plan by little three american auto co's is not accepted by congress Toyota and Ford going be only one left who is racing now. Ford has enough money to last till 2010 but most likelly will cut back to conserve the cash

Joe Gibbs Racing (#11, #18, #20)
Team Red Bull (#82, #83)
Michael Waltrip Racing (#00, #55)
JTG Daugherty Racing (#47)
Bill Davis Racing (#22)
Hall of Fame Racing (#96)
Germain Racing (#13 Part-Time)
