I bought my fully-optioned Vibe GT new, with aftermarket 17-inch wheels installed by the dealer. Out the door for an even $20,000. Very good deal. I installed an Alpine stereo with XM satellite radio and an iPod connection, but kept the very excellent speakers that came with the Moon & Tunes package.
The car has served me well, racking up lots of miles, most on cross-country drives. Upright driving position, very comfortable for me and three passengers.
The engine is fun, though short on torque. So you do a lot of shifting, and the cabin has a buzzy atmosphere. Fine for me, though some people find it tiring. The car is pretty quick for its class, and with the aftermarket wheels handles very nicely.
Big complaint though: when the road is wet, it's nearly impossible to get adequate grip when starting from a stop.
I love the real plug for a power cord and the automatic lights. The interior is identical to my brother's Matrix. The hard plastic in the cargo area is great for clean-up, but lets stuff roll all over the place if you don't have nets.
The air conditioner has been a weak point from the first day I owned the car. On 100-degree days, it just barely keeps things cool. It could be there's a malfunction of some kind; I've never had it checked. The quality of the paint is also less than stellar... chips and scuffs easily.
Premium fuel is recommended, and I've always used it. But the mileage is pretty decent. On highway trips, even driving at 75 or 80 mph, I often get close to (or exceed) 30 mph.
Overall, for the money I paid, I've been very pleased with the car.
