Buick Rendezvous Real Gas Mileage: Pros
YearBody/PowertrainComment
2005 4dr SUV 185-horsepower 3.4L V6
4-speed automatic FWD		 Generally good mileage. I generally have a light to medium foot, will use A/C, and most driving is a mix of suburb and hwy. Tend to get just over 20mpg. On strict highway driving with a load, get 23 plus. see full Buick Rendezvous review

2005 4dr Sedan 239-horsepower 4.6L V8
4-speed automatic RWD		 The V-8 is thirsty for city driving. The extra power would be nice for highway & mountain driving, though. see full Mercury Grand Marquis review
