Re: Marcus Ambrose to test NASCAR???
Marcos is contracted to Ford, and if you extend the links its possible he could get a run in a Winston Cup team in the same brand of car, if that was his bent, and there was an opportunity available.
With some drivers, the achievement of a championship can dull the desire to keep doing it to win a second one. Perhaps Marcos is testing the waters for the future....
All is not as it appears. Trust no-one
