Buick Rendezvous Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
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
