For this particular unveiling, GMC invited us to Palo Alto, California for a couple days of driving variants of the all-new 2007 Acadia, with time left over for some seat time in the rest of the brand's lineup, including the redesigned 2007 Sierra pickup. Our time piloting the Acadia, in base SLE front-wheel-drive and SLT1 all-wheel-drive guise, took us along the sunny highways and back roads outside Palo Alto, providing ample opportunity to evaluate the vehicle's road manners and level of athleticism.
