Minor equipment revisions mark Buick's crossover SUV for 2005. Rendezvous shares GM's front-wheel-drive minivan platform with the Pontiac Aztek, but is four inches longer to allow 3-row seating. CX, CXL, and top-line Ultra trim packages offer front-wheel drive with optional traction control or all-wheel drive without low-range gearing. CX and CXL come with a 185-hp 3.4-liter V6. Ultra uses a 245-hp 3.6 V6 that's optional for CXL. All models have 4-speed automatic transmission. Standard 17-inch wheels replace 16s for '05. ABS, front side airbags, and OnStar assistance are optional for the 2WD CX, standard otherwise. CX and CXL come with a 3-place 2nd-row split bench seat that slides fore and aft. Twin 2nd-row buckets and a 2-passenger 3rd-row seat are standard for Ultra, optional for the others. The same applies to rear obstacle detection, satellite radio, and head-up instrument display. Rear DVD entertainment is available except on CX. Also for '05, the CXL group adds a wood/leather steering wheel and woodgrain interior trim, while the CX adds an optional sunroof. A navigation system is available for CXL and Ultra.
