The 2005 GMC Envoy XUV gets a few upgrades this year, including new, more comfortable seats, a CD/MP3 player, full-length side curtain airbags to go with the dual front bags, and interior wood accents in the upscale SLT trim. Not your average mid-size SUV that offers both rear-wheel and all-wheel drive, what makes the Envoy XUV unique is its ability to change from a five-seater SUV to a pickup truck with up to 8 feet of bed length with the push of a button.

The roof over the cargo bed retracts into the main roof, while the rear window rolls into the tailgate. A Midgate divider with window that separates the cab from the bed folds down (the window powers down into it) along with split-folding rear seats, doubling cargo capacity from 40 to 80 cubic feet. The bed itself is waterproof and features drainage holes and movable tie-downs. With the rear window down, the tailgate extends out for two extra feet of space, or, with the window still rolled up, it can open to the side like a conventional SUV. Power comes from a 4.2-liter, 275-hp V6 or 5.3-liter, 325-hp V8 with displacement-on-demand. Both engines are matched to a 4-speed automatic. The 2005 Envoy XUV is available as a base SLE or upscale SLT, which adds leather seats and a power driver's seat to base features, such as ABS brakes, a full power setup, and dual-zone climate control. Traction control is optional.

Its incredible cargo versatility is high point for owners of the 2005 Envoy XUV, who also use the bed for expansive tailgate parties and for camping (a tent cover and mattress are offered as options). They also like the acceleration power and confident handling. Downsides include maneuverability and noticeable body lean around curves, low fuel economy, and a desire for more towing capability.
