Faults:

When the car was brand new, there was a blown fuse that caused some of the interior lights to be off or dim. Easily fixed.

GT model does not come with a spare tire, but is supposed to come with a GM fix-a-flat solution. Mine did not. Despite repeated attempts to get this, the dealership couldn't obtain it for me.

Eventually I spent 500 additional dollars and bought a spare.

At 15000 miles, started smelling antifreeze. Took it into the dealership, they claimed the water pump itself was leaking (very surprising for so low mileage) but, whatever the caused, they fixed it for no charge in less than 24 hours and the problem hasn't returned.

The leather develops wrinkles too quickly.

Some of the body work doesn't fit right... there are small gaps in the rear and front bumpers.

But it has started 100% of the time, and the coolant leak was very slight and never caused any problem.

General Comments:

The car is brilliant. When price is taken into account, it's the best car in the world, objectively speaking. That's not a dramatic statement. An examination of everything this car is good at, a comparison to competitors and of course, a consideration of value, will result in this judgment.

The engine cannot be ignored. It's not the best V8 in the world, but it's the best one underneath the Corvette (which is 45k--15k more than the base G8 GT). It has power, everywhere. My other car is a Subaru WRX, so I've been used to a peaky powerband, and the combination of the 6 speed automatic transmission with an engine with an amazingly flexible powerband means that at any point you can have huge power. The acceleration from a dead stop is very good, but the high speed acceleration is phenomenal. There are cars even in its price range that can out accelerate (citing, say, an STi) from a stop, but from a 100 on, the car pulls hard.

The fuel efficiency is phenomenal as well. It's rated at 18/24, as I recall, but I routinely get 30mpg on the highway (although, in fairness, the town is about the rating--it's hard not to keep it in 1st or 2nd to feel the power).

The handling is terrific--and don't get me wrong, I'm not saying you're going to turn top lap times in your G8--but it's terrifically fun. The car just handles so brilliantly at 9/10ths. It lets go of the grip gently, and in a balanced fashion--it's an excellent drift car. The engine and transmission are flexible enough to let you steer with the throttle during a drift at any speed.

The interior is quite nice. A moderate overuse of plastic, which is common in luxury cars under 50,000 (having tested IS350s, G35s and 335is rather extensively before this purchase), is present. The large red display in the middle of the console annoys many, but I appreciate little quirks. The gauge cluster is adequate, but the gauges, like in most cars, are in the wrong places. The speedometer or tachometer should be the middle of the cluster (depending on whether or not the car is an automatic/smg or manual), but instead, the speedometer and tachometer are on the left and right, while a helpful, though misplaced, data display is in the middle--that's okay, but that's not performance minded--go check out a Ferrari or Porsche gauge cluster to see it done right.

The manuamatic/tiptronic shift area is reversed. It's more intuitive, in the real world, to put upshift closer to the driver and downshift farther away.

The front bumper is too low for the real world. There's no paint left on the bottom of mine.

Wind noise is too loud--not more than an ordinary car, but this is a grand tourer, and it ought to be quieter.

Ride is nice, about where it should be for this segment.

Tons of room on the interior and trunk.

I love the heated seats, fully auto dual zone climate control, LCD display, onstar and remote ignition.

I could probably write a lot more, but this should be an adequate review for most potential G8 buyers.

Faults:

Nothing. Brand new.

General Comments:

First of all, I DO NOT own a G8. I normally don't put much stock in reports based on test drives or rentals, but was so impressed with the two G8's I have driven that I wanted to add a review. There are so many in my area that I am surprised there are as yet no reviews on this incredible car.

I drove both a base V-6 and a 361hp GT model with the silky smooth 6-speed automatic. The V-6 was more than adequate in power, and the V-8 will give the Mustang GT a very good run for its money, if not leave it far behind.

The Aussie-based car (it's basically a Holden) is very aggressive, and easy to mistake for a BMW from the front. It is clean, sporty, and one of the true sports sedans of our day. The price (between about $22,000 for a base and $29,000 for a GT) is less than HALF of BMW's that are not as fast or good looking.

I found the GT ride just a tad harsh, but not nearly as bad as my 2007 Mustang. It had a very taut, sporty feel and handled better than the Mustang. The response was quick and instantaneous even with the V-6. The transmission is typical silky smooth, quick shifting GM perfection. I also own a 2001 Pontiac and a 2003 GMC, and nothing beats GM automatics for smooth and precise shifts.

Due to escalating fuel prices, I'd recommend the very affordable and more economical 6. It was quite sporty in feel and response, and no slouch in acceleration. The prices of these cars are highly competitive with Mustang, Charger, Camaro, Fusion and Malibu.

Since I only drove these cars about 10 miles each, I cannot give any objective review on reliability, however both our current GM's (including the 8-year-old Pontiac) have been 100% reliable with never a single problem of any kind. I feel the G8 will be a very solid and reliable car.

My ONLY gripe with these cars is the NAME. Pontiac has started using names that sound like TAX FORMS!! G5, G6, G8. I'd love to see this car called something more appropriate to a sport sedan, such as Bonneville or Grand Prix.
