The 2006 Pontiac Vibe is a sporty wagon/mini-SUV or crossover.  Whatever you decide to call it, it's been a big hit for GM, appealing to a youthful market looking for zippy performance as well as practical cargo hauling versatility that suits an active lifestyle.
The 2006 Vibe comes in three trims -- base front-wheel drive, all-wheel drive, and the sporty GT.  All feature a 1.8-liter, 4-cylinder DOHC engine, but the GT's has been souped up to hit 164-hp to the 126-hp in the front-wheel drive and 118 in the AWD (undoubtedly because of the extra weight).  A 5-speed manual is standard, except on the GT, which comes with a 6-speed manual transmission.  
New for 2006 are some instrument updates and a more ergonomically designed center console.  Leather seats are a new option as well.  Though the 2006 Vibe comes standard with air conditioning, CD, and power windows, more power features, cruise control, OnStar, and a sunroof are favorite options.  Rear seats fold flat and the passenger seat also folds down for enough room to fit a passed out basketball player.  
Owners love the storage configuration possibilities as well as the overall leg and headroom for passengers.  Gas mileage (30/36 mpg) is outstanding, and the engine is powerful enough to add some zip to the driving experience.  Drivers also like the AWD capability in their 2006 Vibe.  Some common dislikes include excessive road and engine noise and a tendency for a rough ride.  Many want more horsepower.
