Model Overview:

Until Pontiac bit the dust in the wake of GM's 2009 bankruptcy fiasco, the Pontiac G6 was the company's go-to midsize car. In a constant battle to steal sales from the class favorites, the G6 offered unusually tactful styling by Pontiac standards, solid performance from its V6 engines and the availability of a four-seat retractable-hardtop convertible body style. Volume-selling models were the five-passenger sedan and four-passenger coupe.

Unlike the Grand Am that it replaced, the Pontiac G6 had considerably more flavor than a generic rental car. Still, the traditional class favorites topped the G6 in the areas of engine refinement, driving dynamics and cabin materials. The G6 may still hold appeal for used-car shoppers, especially given its likely cut-rate pricing. GM has pledged to continue supporting Pontiac products in its service departments, so a used G6 isn't necessarily a bad idea.

Most Recent Pontiac G6

Based on General Motors' lengthened "Epsilon" platform, the Pontiac G6 was produced from 2005-'09 as a sedan, coupe and retractable-hardtop convertible. For '05, only the sedan was offered; the coupe and convertible debuted a year later. Three main trim levels were offered on the sedan: base, GT and GTP (which became the GXP in '08). Coupes were either GTs or GTP/GXPs, convertibles GT only. Plenty of standard features, such as air-conditioning, full power accessories and CD audio, came on the base model. The GT added niceties such as an upgraded Monsoon audio system. The GXP topped the range with items like sporty exterior styling tweaks and automatic climate control.

At the time of Pontiac's demise, the G6's engine lineup included a base 2.4-liter four (164 horsepower), a 3.5-liter V6 (219 hp), a 3.9-liter V6 available on the convertible only (222 hp) and the GXP's 3.6-liter V6 (252 hp). Four-speed automatics were standard with all except the GXP's V6, which got a six-speed; however, the four-cylinder got an optional six-speed for 2009 that raised highway fuel economy to a laudable 33 mpg. Some power ratings were a bit lower in previous years, notably the 3.5-liter V6, and a manual transmission was available on a limited basis until '08.

In reviews we found that the Pontiac G6 offered generous room for those riding in back, no matter the body style. And we noted that after years of enduring criticism about its overstyled exteriors and gimmicky interior designs, Pontiac stepped up its efforts with the G6. Outside, the G6 had a crisp and sleek look; inside, there was a restrained and attractive layout with none of the traditional dull gray plastic switches. Even so, the G6 still had a few too many cheap plastic surfaces for our tastes.

On the road, we appreciated the low and midrange torque of the 3.5-liter V6, and the ride was smooth. The convertible's optional 3.9-liter V6 should be avoided if possible, though -- it was barely more powerful than the 3.5-liter V6 and got worse fuel economy. Handling was respectable, but we disliked the electric power steering, which was too light and offered virtually no feedback. GT models from 2007 and up had an improved hydraulic steering setup, which we preferred. Along with the enhanced feature content of the later models, we'd recommend focusing your used Pontiac G6 search on the '07 or newer models.

  • Buyer Beware! - 2006 Pontiac G6
    By -

    Ive had my 2006 Pontiac G6 for almost 5 years. Very disappointing and lots of maintenance issues beginning at 12,000 mi. Engine, electronic steering, wheel, and paint issues. Very cheap interior plastic parts that continue to break or pop off, condensation in headlight, and now CD player has quit working altogether. I take care of the cars I buy but this one has been non-stop repair bills.

  • Uh oh - 2006 Pontiac G6
    By -

    Bought this car with 19,000 miles on it. Replaced mirror covers several times. Uncontrollably shakes while breaking. Clicking sound when turning and now with 61,000 miles on it my engine smells of burning and a metal rubbing sound with acceleration. Highly upset and do not recommend to anyone.

  • Super - 2005 Pontiac G6

    I love my G6!! It is the easiest car to maneuver. My husband cant wait til the weekend arrives so he can drive it too...

  • True drivers car - 2007 Pontiac G6
    By -

    The review is actually for a Canadian version of Pontiac G6 SE with Performance Package (3.5L 224-hp V6, hydraulic steering, fog lights; ABS, curtain-side airbags come standard). Purchased just a month ago, and I still cant get over a very competent sporty ride, solid build, just the right suspension, firm cornering, and loads of torque for sudden acceleration. Very roomy too, and all controls are nicely placed. The car is a pleasure to look at and a joy to drive!

  • First "NEW" Car - 2006 Pontiac G6
    By -

    This was the first NEW (Brand New) car that I had ever purchased. I normally will pick up a car that has a year or so on it to save a few bucks - But No Regrets! This car is a ton of fun to drive and handles incredibly well on the road. In fact, I am in Wyoming, and the Winter driving was as good as the Spring. The traction control is awesome! The only problem that I have run into is with the Indexing Windows. Problem being, they freeze in Wyoming and I am afraid I am going to break a window to open the door. The solution, Remote Start! Wish I would have gone for the GTP and Climate Control, but other than that, no regrets!

  • Not perfect, but very good! - 2007 Pontiac G6
    By -

    Bought one of these cars off-season last year, fully loaded with the Monsoon stereo, heated leather and low mileage on the 3.9L upgraded V6. This is my mothers "fun car," replacing a workhorse S10 pickup. We test drove all sorts of cars, and were looking at a Miata when I found this at a local dealership. She fell in love with it at first sight and after driving it, had to have it. This thing moves like a scalded cat and the touring suspension soaks up the bumps great, even with the 18" wheels. The transmission is smooth and you can "row" the automatic if you want. We got it as a CPO with extended warranty, to hedge against any mechanical or electrical gremlins.

  • G6 GTP Sedan-Great Value - 2006 Pontiac G6
    By -

    I had a 2004 Mercedes C320 and even though it was rock solid and handled the road well at high speeds. It was overpriced and a piece of garbage with all sorts of mechanical problems. Total waste of money. I leased an Infinity G 35 Coupe and loved the car. It was fast, beautiful, and fun to drive. The reason why I got rid of it because it was not ingress and egress friendly for babies. G 6 GTP has almost identical performance 0-60 6.2 seconds compared to G35 6.1 seconds. The G 6 GTP Sedan is beautiful inside and out and offers outstanding performance (Faster than the 2004 mustang gt with the 260 horse). I know beacuse I beat them all the time. G6 GTP really changed my views of American cars.

  • Great car - 2005 Pontiac G6
    By -

    Ive owned my G6 3 years now. Purchased a fully-loaded GT with leather, panoramic roof, chrome wheels, etc. Closing in on 66k with nothing but routine maintenance. Daily driving is highway driving in Dallas rush hour 22 miles each way and average 29 mpg. Extended trips average 32 mpg as long as I stay below 70 mph. Panoramic roof is great in spring/fall.

  • Florida brings out best and worst - 2006 Pontiac G6
    By -

    I like the cars responsiveness to the throttle, it is almost intuitive. I like the size of the car in a metro area. My wife drives it most of the time and really looks sporty in the red car with chrome wheels and sunroof open. I dislike the poor visiibility out of the rear window and the difficulty getting into the back seat. It needs a bit more head room back there. There have been absolutely no mechanical problems. The red color makes it hot to touch in the FLorida sun. The car is hot inside when you get into it. It needs heavily tinted windows.

    Absolutely love the car. It is a very good riding car as we take it on all vacation trips. Quiet & exceptionally smooth ride! Highway mileage is normally 35 mpg running 65 mph... Thats nice on trips too.
