  • GXP - A Love, Love Relationship - 2005 Pontiac Bonneville
    By -

    Most people acquire an automobile to transport the family from point A to point B. This Bonneville does that but with a lot of excitement thrown in. You find that any excuse to use this car is justifyable. Forget that its often less expensive to go by air. Who cares, its too much fun to drive especially in this GXP. Do not buy this car without heads up display and XM radio. The soft two tone leather seating is a great standard feature adding to superior driving experience.

  • Good Vibes - 2005 Pontiac Bonneville
    By -

    The Bonnie Gxp is a blast to drive. With the sweet sound of its pipes, I feel like it;s 1965 again. It has good power,could use more torque down low, but its a dohc engine; and really starts to cook @ about 3500-4000 rpm.I love the styling. Looked at the Chrysler 300; but couldnt handle the cheese grader front end. And please; the Toyota Avalon is just plain ugly! The Bonnie has a busy interior, but I love the red dash at night; XM radio is fantastic. Gas mileage is only ok but it is a big heavy car with a v8. But like the man said "I feel good when I get in, and I feel good when I get out" If your looking for a larger car that handles like a BMW;w/good power;nice ride,big trunk; GXP!

  • Pure Fun - 2005 Pontiac Bonneville

    I went from a 2001 Yukon to my 2004 Greystone Metallic GXP. The size was the toughest adjustment, but the power and handling made up for the loss of room. Its nothing but muscle and fun to drive. Theres nothing better then merging into fast moving interstate traffic and listening to the growl of the Northstar at its best! I have had it in for warranty work four times since purchase in six months for silly minor things and one major A/C water leak which the dealer kept in the shop for a week! Probably more of a dealer issue. The brake rotors rust as well and the dealer thinks its acceptable.

  • nice car-poor quality - 2005 Pontiac Bonneville
    By -

    Love that motor, handles nice with a good ride, overall a rewarding car to drive. Quality is poor, car is midnight blue and the primer shows through all over. GM wont respond so Im going to BBB for buy back. 13 new GMs in last 20 years and this is how they treat return customers? Very unhappy with the fact they wont meet with me. Time to look at the Imports.

  • love it - style, performance, economy - 2005 Pontiac Bonneville
    By -

    This car is great. I bought with 90K. It now has 102K. I love the style. Very stylish car. Its big!! Its comfy. It has a very quiet cabin. The gm 3.8 is an amazing engine. Actually got 30 mpg when doing a highway trip of 480 miles. with 16 gallons of gas. It has a big gas tank at 18 gallons. Dont need to fill up much. Normal MPG is about 25 with highway/city mix and not winter out. One problem it died on me on the freeway. Kinda scary. It was the Mass airflow sensor. It happened out of nowhere. No engine lights. I would replace this at 100k miles or sooner. Thats when it died on me. Besides for that no problems. You can probably have autozone replace for you.

  • We love this car - 2005 Pontiac Bonneville
    By -

    We purchased this car in Feb 2005; we have had abolutely no troubles with it. It is fun to drive, reminds me somewhat of the muscle car era I grew up in with a touch of class & luxury. Ours is Black with gray/black leather interior. We get the oil changed every 4-5 months as we dont drive a lot of miles, pleasure only, three vacation trips of 1,500-1,600 miles or so included in the 14,700 now on the car. Actually it is my wifes car; her previous car was a 34,000 mile, T-Top 1996 Camaro; she didnt drive that one much either; about 6 vacation trips in that car; it had the 3000 V-6

  • Wonderful touring sedan! - 2005 Pontiac Bonneville
    By -

    What a wonderful car. I am so very pleased with my Bonneville SLE, and have driven on 3 over 500 mile trips in my SLE and just enjoy its great handling (FE2 ride and handling package) and great torque from the 3.8 Series II V6. I never forget I am in a Pontiac. I have put about 8000 miles on mine and really like its driving dynamics. It rides wonderful on the highway and does not comprise on curves. It cuts coners very stable with almost sports car like feedback and performance. Overall it is an impressive vehicle and classic American styling also get some thumbs up. I am very sad to see such a great large sedan be taken out of production! Pontiac bring the Bonneville back, I am waiting!

  • Love this car - 2005 Pontiac Bonneville

    Bought this GXP in Feb 2005; actually bought it for my wife; not only does she love it , but I like to drive it; I grew up in the muscle car era and this reminds me of it. Love the Northstar V8. The car has been very reliable with decent mileage considering the power available City 14.5/Highway about 23. Love the HUD, memory driver features(seats & mirror, plus radio. Ours is Black with Grey interior; its a real head turner. The car is garage kept and has very low mileage (driven to/from grocery store by a little old lady; we are in our late 60s). Her previous car was a 1996 T-Top Camaro RS, with 3.8L V-6, also low mileage, 10 years, 34,000. We plan on keeping the GXP a Long time!

  • I Love my Pontiac Bonneville - 2005 Pontiac Bonneville

    I had a 1995 Bonneville and with its mileage at 128,000 I knew it would last much longer but in 2005 they made the last one so I had to make a decision and decided to get the 2005. I absolutely love it. Cant say enough about it. I can go a week on a tank - it gets me about 26 miles/gallon around town and to work. Its comfortable to drive and even spend time in parked watching movies on a dvd player/doing computer work, etc. Love it ! Bring it back so in ten years I can buy another! GM must be slowing down selling cars because they are lasting longer!
