2005 Chevrolet Suburban 1500 LS Rwd 4dr SUV (5.3L 8cyl 4A)
We bought this vehicle new in 8-05 and have been very pleased. Reliability has been top notch with not one issue at almost 50,000 miles. It's been on a 4,400 mile vacation round trip with a 20 MPG highway rating driving thru a stretch of interstate at 65 MPH. Most of the driving has been in the Baton Rouge metro area.
Looks, comfort, reliability, performance, and exterior body integrity.
Make a hybrid available at all levels. A large segment of SUV drivers might be willing to pay more for a vehicle up front for better fuel economy. It'll never be a Prius, but 20mpg overall certainly beats 14.
