V8 Has Plenty Of Power For Towing. Handles Great For A Suv. by Mike
 — All leather interior with power/memory seats. Everything is power/automatic. Very comfortable ride for a family of 4. Little extras like the built in air compressor is great for inflating bike tire... Read More

2004 Buick Rainier

It has been over 80 years since Buick last made a truck, so the debut of the truck-based Buick Rainier has a special place in the carmaker's history.  The new mid-size SUV maintains Buick's reputation for subtle luxury, comfort, and reliability.  Even the new front end, with its oval grille, four headlights and 17-inch tires seems classically elegant, rather than aggressive sporty utility vehicle
The Envoy and Trailblazer are GM cousins to the 2004 Rainier, but the Rainer only comes in standard wheelbase, and not extended, and thus only features two rows of seats.  The CXL trim is offered in either rear-wheel or four-wheel drive and comes standard with a 4.2-liter, 275-hp V6.  While the Envoy and Trailblazer feature a V8 only in their extended cabs, the 2004 Rainier's shorter SUV has the same 5.3-liter, 290-hp V8, making it a powerful and potent hauler.  A 4-speed automatic is the only transmission.  Buick's new QuietTuning is used in the Rainier, adding thicker seals, more insulation, and heavier body plating to reduce road and wind noise.  
Since it's only available in one trim, the 2004 Rainier went all out in terms of convenience features.  ABS, load-leveling suspension, and front side airbags are standard, as are countless power features, memory settings, OnStar, compass, rear audio controls, heated mirrors, driver information center, and leather upholstery.  Storage is available in the trunk, overhead and center consoles, and in a cargo well.  
The 2004 Rainier seems versatile and practical, while not skimping on creature comforts.  Owners say it is extremely quiet and the ride is smooth.  Storage space is optimal and the towing power of the V8 a big bonus.  Gas mileage suffers, particularly with the V8.  Cupholders are poorly placed near the shifter, and the plastic dash looks cheap.
