Overview & Reviews

The Bonneville gets only minor changes for 2003. Base SE models now sport newly styled 16-inch steel wheels and a standard AM/FM/CD stereo, while all models can be upgraded with optional XM Satellite Radio. Previously standard side airbags are now optional on SE and SLE models.

• Loads of gee-whiz features, solid handling and drivetrain, excellent crash test scores, large trunk.

• Average interior materials, overly complicated controls, poor resale value.

  Nice ride - 2003 Pontiac Bonneville
  By tony - October 11 - 6:46 pm

  I traded my 2004 Grand Prix for this car. It’s a much better ride than the GP. Fuel economy 23 city 28-29 highway. 1 problem since owning was a repair of $46 dollars. Other than that it runs like a top. Comfort. It rides better than my 2002 Concorde Limited.

  Sweet n powerful Bonnie - 2003 Pontiac Bonneville
  By Ming - April 9 - 10:00 am

  I love these cars. Great tire squealing acceleration off the line, none of that "240 hp" that only comes 10 minutes into driving it up to 10,000 rpm. Instant power. The interior is comfortable, but the headrest is a little odd - it supports my head only when tilted forward. Love the heads up display and at your fingertips radio controls. Only problem was insulation in the trunk at one spot leaked. Fixed under warranty.

  Love my Bonneville - 2003 Pontiac Bonneville
  By Honeypml2003 - September 18 - 2:46 am

  I really love my car! I have had it for over a year and have driven it to death. The only problem is that the fuse to my interior lights keeps blowing. Other than that it is comfortable and a fun car to drive. When you keep the oil changes current it really accelerates! Gas mileage is okay! Oh and the plastic things in the car keep breaking (cover for the vanity mirrors for example) Other than that it is wonderful and a pleasure to own! IT is VERY reliable!

  Nice Car - 2003 Pontiac Bonneville
  By shumpert - May 17 - 10:00 am

  First Pontiac owned, good power, handling is excellent for a full size car, quiet and interior styling good. back seat is a little rough for 6 footers, and not to thrilled about placement of the battery underneath the left rear passenger seat. Otherwise, a fine automobile for the price.

  Sweet Bonnie - 2003 Pontiac Bonneville
  By ProvemWrong - July 10 - 10:00 am

  I traded a Regal for the Bonnie. so glad I did. This car is more stylish, great comfort, excellent layout inside and out, the butt warming seats and independent climate control keeps the old lady happy, better handling and suspension with more power. Lots to enjoy from the Dash lighting to the leather comfort ride. Easy cruise... XM Radio and moon roof. Great car.

  Supercharge It! - 2003 Pontiac Bonneville
  By leaseman - May 2 - 2:00 am

  This is a handsome vehicle now that the universally hated body cladding has been replaced with simple molding. The drivers seat is like a cockpit with soft, comfy leather seats and an assortment of lights and gadgets that will make any techie drool. Acceleration is snappy with the supercharged engine, the only noticeable lag being when the car was being driven aggressively up a steep hill. This is a fine American performance sedan.

  By TOPTIMLRD - April 3 - 2:00 am

  Fun to drive. Doesnt fel like a large car. The 240 horsepower allows plenty of throttle response. Very comfortable interior, seats could use a little better bolster however. Great driver interface, great sound system.

  Our 03 Bonneville - 2003 Pontiac Bonneville
  By Robert - February 13 - 3:06 pm

  Have mad some very minor mechanical issues. Seats could use slightly larger bolsters. Dual climate system could be a bit more effective. Overall very pleased with the car. Very powerful for a six cylinder. I actually do not mind the premium fuel requirement as it gets very good gas mileage for such a large car. Averaging 24 miles to the gallon with a mix of hwy and city driving.Could use a bit more knee room on passenger side (I am 61").
