After sounding the trumpets for the future introduction of no less than 14 crossover vehicles, GM has let us know what a couple of them will be named. The eight-seat GMC Acadia we posted on last week and the upcoming Saturn Outlook will be joined by the Buick Enclave, which is reportedly replacing both the Ranier and the Rendezvous when it reaches dealers in Spring of 2007. The Saturn Outlook will go on sale first in the fall of 2006 and the GMC Acadia will wait in the wings until the end of 2007. Hopefully the staggered rollout means each model will be markedly different from its platform mates. The Enclave's styling, according to Edmunds, will be based on the Centieme concept (shown) that debuted at the 2003 Detroit Auto Show.
