If the 2007 GMC Acadia looks vaguely familiar, it's because it shares its GM Lambda underpinnings with the recently launched Saturn Outlook and upcoming Buick Enclave. Sales of the General's minivans (Chevrolet Uplander, Saturn Relay, and others) never amounted to much thanks to competition like the Honda Odyssey and Toyota Sienna, so they've been replaced by this new breed of large crossover vehicles. Blending the style of an SUV with the functionality of a minivan, the GMC Acadia and its brethren aim to attract new buyers wanting utility without the minivan's stigma or thirsty reputation of large SUVs.
