Sticklers for ergonomic detailing may quibble with the positioning of some of the minor control switchgear in the G8's interior. While its standard OnStar system provides for proprietary hands-free calling and Turn-by-Turn navigation, there's no stand-alone navigation system.

Used 2009 Pontiac G8 Expert Review

Attempting to bolster its image – and drive a whole new generation of performance-oriented buyers back into its dealerships – GM's self-proclaimed excitement division last year added the G8 sport sedan to its U.S. lineup. Built in Australia and based on the popular Holden Commodore model, Pontiac's new flagship is its first rear-wheel-drive sedan in several years and is available in three trim levels, a V6-powered standard model, the sporty V8-powered GT and, for 2009, an all new high-performance GXP trim with a proper six-speed manual transmission. The G8's aggressive appearance, impressive array of features, superb handling dynamics and attractive pricing should also help it appeal to those who might want something with the performance and feel of a European sport sedan but at a lower price.

Driving the Used 2009 Pontiac G8

Based on GM's newest global rear-drive platform (which will also underpin the upcoming 2010 Chevrolet Camaro), the G8 has a dynamic character that's more in line with a premium European sport sedan than a domestic four-door model. Whether you opt for the electrifying acceleration of the GT or prefer the more economical but still impressively quick base version, the G8's fully independent sport suspension is tuned to deliver a great combination of control and comfort that works as well on the freeway as it does on your favorite twisty two-lane highway. The G8's variable-ratio power steering feels positive and linear, and its anti-lock disc brakes slow it with confidence – particularly the larger units used on the GT. Toss in near-ideal weight distribution, driver-selectable stability and traction controls and multi-mode automatic transmissions, and either of these Pontiac sedans has the tools to deliver performance that will impress even the most demanding enthusiast.

Favorite Features

Active Fuel Management System
Complementing its outstanding power and torque characteristics, the GT's 6.0-liter V8 also is fitted with Active Fuel Management, a computer-controlled mileage-optimizing system that allows seamless transitions from eight-cylinder to four-cylinder operation under lighter load conditions.

Driver Shift Control
Both of the G8's automatic transmissions incorporate tri-mode Driver Shift Control circuitry. In addition to "normal" and more-aggressive "sport" programming, each has a manual-style gate that lets the driver select a gear that is then held until the driver shifts, even if that's at the engine's redline.

Used 2009 Pontiac G8 Interior

Purposeful and understated, the G8's spacious cabin reflects its athletic personality in charcoal and grey tones (or optional charcoal and red leather) set off by brushed-aluminum-look accents. Main control layouts are good, the white-on-black gauges and red LCD readouts are legible and the supplemental switchgear is generally arrayed in a user-friendly manner. Highlighting the G8's features are well-bolstered, power-adjustable front bucket seats that provide excellent comfort and support, whether covered in standard cloth or available leather. The expansive rear bench can easily and comfortably accommodate a pair of six-footers or take three average-sized adults on shorter treks, while its cavernous 17.5-cubic-feet trunk handles suitcases and golf bags with equal ease.

Used 2009 Pontiac G8 Exterior

The 2009 Pontiac G8 makes a powerful but tasteful visual statement, complementing neatly tailored bodywork with prominently flared fenders, a modest decklid spoiler, integrated side sills and functional cooling vents on its hood and front flanks. The face is pure Pontiac, highlighted by projector-beam headlamps, a signature dual-port grille treatment and an equally bold lower air intake. Both G8's wear 18-inch alloy wheels and 245/45 tires, although all-season rubber is replaced by a stickier, summer-spec alternative on the GT. Rear details also differ slightly. The V6 has conventional red taillamps and dual chrome exhaust tips while the appropriately-badged GT gets clear lens covers and a quartet of chrome tailpipes.

Used 2009 Pontiac G8 Standard Features

Apart from their respective drivetrain differences, both G8 models share a common and comprehensive array of power assists, a steering wheel with audio and cruise control buttons on a tilt and telescoping column, trip computer, anti-lock disc brakes, StabiliTrak stability control and front, front-side and side-curtain airbags. All G8's also come with a one-year subscription to OnStar's Safe and Sound service. The base car has single-zone air conditioning and a seven-speaker Blaupunkt AM/FM/CD/audio package with iPod/MP3 input and XM Satellite Radio, while the GT has dual-zone climate control and a more powerful 11-speaker sound system with a six-disc CD changer.

Used 2009 Pontiac G8 Options

The well-equipped G8 offers relatively few extras. Base-model buyers can opt for the Comfort and Sound Package, which includes dual-zone automatic climate control and the upgraded Blaupunkt audio with six-disc CD changer of the GT model. Either G8 can be ordered with a power sunroof or the Premium Package, which includes heated and six-way power front seats, leather upholstery and trim and a fold-down rear armrest with trunk pass-through. GT buyers can also choose the Sport Package, consisting of metallic pedals, split-spoke machine-faced aluminum wheels, sport steering wheel and 19-inch wheels with 245/40WR19 performance tires.

Used 2009 Pontiac G8 Engine

Each G8 model gets a unique engine and transmission combination. The entry-level matchup is a 256-horsepower, 3.6-liter V-6 and five-speed automatic transmission, while the GT comes with a 361-horsepower, 6.0-liter V8 backed by a six-speed automatic. Both transmissions feature multi-mode Driver Shift Control programming, but only the V8 also has GM's Active Fuel Management system to help bolster its operating efficiency in cruise mode. Even the base G8 V6 is an energetic performer, capable of accelerating from zero to 60 miles per hour in a brisk 7.8 seconds, yet EPA-rated at 17 mpg city, 25 mpg highway. But the GT is the real star here. It can nail that acceleration benchmark in a scant 5.3 seconds while earning relatively respectable 15 mpg city, 24 mpg highway ratings from the EPA.

3.6-liter V6
256 horsepower @ 6300 rpm
248 lb.-ft. of torque @ 2100 rpm
EPA city/highway fuel economy: 17/25

6.0-liter V8
361 horsepower @ 5300 rpm
385 lb.-ft. of torque @ 4400 rpm
EPA city/highway fuel economy: 15/24

How Much Does the Used 2009 Pontiac G8 Cost?

The Manufacturer's Suggested Retail Price (MSRP) on a Pontiac G8 runs from just under $28,000 for a V6 to slightly over $31,000 for the V8-powered GT. Pontiac is touting the GT as the most powerful car you can buy in America for under $30,000 and, even fully loaded, it will still be less than $35,000. Those numbers – especially the GT's – make this pair quite attractive on initial price, but the long-term picture is a somewhat mixed bag. Although the GT is projected to fare slightly better than the V6, the retained-value percentages on both G8s are expected to be somewhat lower than comparable versions of the Dodge Charger in SXT and HEMI-engined SRT8 trim levels. Conversely, the residuals of either version of the G8 should marginally exceed those of the Nissan Maxima in SE or SL versions.

2009 Pontiac G8

"bargain of a life time"

Quick, comfotable, reasonably economical & classic
too much brake pedal travel/stops well .
I have owned this Pontiac since September 2008, repairs & maintenance have been very minimal. I am retired & have to invent reasons to drive it. I average about 3500 miles per year of pretty easy operation. When I look at what you can buy for 35K $. I will be keeping this car unless some thing goes terribly wrong. still feels new to me comfortable & averaging 21.5 mpg.

"Best Car I've Owned"

Powerful V6, Spacious, stylish
Not great in snow, some repairs are pricey
This car has been an amazing car since I purchased it at the dealer in 2015 with 85,xxx miles on it. I've done ZERO major repairs (engine/transmission-Knock on wood), but have had some minor repairs needed. (Sway bars, tie rods, speed sensor). The most expensive item on this car was the front struts which cost about $700. This car provides you with everything you need. its very spacious, comfortable, stylish, and provides a great amount of power for a V6. If they continued to make this car, I wouldn't purchase anything else.

2008 Pontiac G8

"One of the top vehicles GM has produced"

fast, fun, reliably, roomy
seat quality, paint quality
I purchased this car new in 2008 and have been extremely happy ever since. This car is reliable, fast, efficient, great options, and has great performance numbers. 118,00 miles in, the car has had no major issues, just things that come with wear and age. It has plenty of room front and rear to comfort 4 full-sized adults and had comfortable seating all around. gas mileage has only gotten better with miles, averaging right around 20 with mixed city and highway driving. There are two reasons why the quality rating is a 9/10. 1st, the front seat material hasn't stood the test of time like I thought it would due to the fact i tell a noticeable comfort difference from the seat foam being worn down. The 2nd issue comes from the soft paint on the car, which was a known issue on the 2008 and 2009 G8 line-up. The paint from the factory was a bit soft, allowing more rock chips and road wear to be seen/noticed on the front and rear of the car. overall, a fantastic vehicle.Read less

"Best Car you will drive!"

Very comfy, outstanding performance for a V6.
Personally the V6 model is enough for me, people say oh it is just a V6 and isnt the V8. Personally I dont need a V8, but if you are looking for something good on gas and sporty and fun this is what you are looking for. My G8 is an up scaled model of the Base, mine has a sun roof and premium audio, and last but not least premium sports package for the interior. The car is not that hard to drive, and it gets a lot of looks. People this car was only made for two years, and it is like a gem you cant ever find anymore now a days. The comfort of the car was amazing, and performance was so fun for me, sports mode is very quick and responsive. Manual mode was fun as well. This car is great for show and fun. Personally would buy another one.Read less

"My G8 GT gets better with age"

The G8 GT merges into traffic nicely.
No GPS system.
I am the original owner of the G8 GT, having bought it for cash on July 6, 2009. It has been serviced by a dealer with oil changes every 4,000 miles or less. The car has lots of get up and go, if you need it. I am 75 years old and no longer need that much power. Car has white exterior and black leather seating with heated front bucket seats, all in very good condition. On Star and satellite radio, 11 speaker Blaupunkt system 230 amp and sub woofers, 6 disc CD player. The G8 GT has always been garaged.
