2003 Buick Century review: Our expert's take

Posted on 10/23/2002
Vehicle Overview
Last reworked for the 1997 model year, Buick’s mainstay midsize front-wheel-drive sedan has been the company’s most popular model. Older buyers, in particular, tend to like the Century’s front bench seat, which offers space for three occupants.

Antilock brakes are no longer standard for the 2003 model year. The Century’s body gets a fresh look with a new graphite/chrome grille, chrome door-header openings, and new body-colored fascias and side molding. Additional interior trim padding aims to improve head-impact protection. New wood-grain switch plate covers are installed, and two new body colors will be offered.

Constructed from the same basic design as the sportier Regal, the four-door Century is more conservative in appearance, which helps account for its appeal to older buyers. Beneath the hood is a 3.1-liter V-6 engine, which differs from the Regal’s 3.8-liter power plant.

The Century has been a long-time rival of the full-size Buick LeSabre in the race to be the most popular Buick model. In its regular form, the Century’s front bench seat provides six-passenger capacity, which is offered on only a handful of midsize models.

Although its styling is related to that of the jauntier Regal, the Century has a different grille, rear styling features, body trim and wheels. That makes it relatively easy to tell the two apart at a glance. Both Buick sedans are 72.7 inches wide, stand 56.6 inches tall and ride a 109-inch wheelbase, but at 194.6 inches long overall, the Century is a little shorter than the Regal.

Other than the Century’s bench seating — vs. the Regal’s sportier front bucket seats — these cars’ interiors are very similar. The Century comes in a single trim level, but Custom and Limited option groups are available. All versions of the Century have a three-place front bench seat with a folding center armrest that includes storage space. Trunk capacity totals 16.7 cubic feet.

Standard equipment includes dual-zone air conditioning, a tilt steering wheel, remote keyless entry, an AM/FM radio, and power windows and door locks. The Custom package adds folding power mirrors, cruise control, a cassette stereo and a six-way power driver’s seat. The Limited sedan features leather-surfaced seat trim and chrome wheel covers. GM’s OnStar communication system is a factory-installed option.

Under the Hood
A 3.1-liter V-6 engine produces 175 horsepower and drives a four-speed-automatic transmission. The higher-performing Regal, by comparison, holds a 3.8-liter V-6.

Antilock brakes with traction control are optional. A side-impact airbag for the driver’s seat is optional with a leather-trimmed interior.

Understated Elegance

All these years of me looking right through most any generations of Buick Century’s until I inherited this 2003 Century Custom. I was dumbfounded at the reliability, and believe it or not, the subtle styling & major comfort & ride. Aside from owner neglect, the car started right up after having sat for months and idle for weeks in literal sub-zero temps as if it were in a heated garage all this time. I expected a rough & rattling ride on my first drive home with it, but I was amazed at the quietness & the gliding of the suspension. These Century’s are certainly an under-appreciated vehicle.


Love her

I have owned this car for more than 4 years now. I call her my "grandma car" but she kicks arse. Im a sungle mom amd my youngeat has special needs we do 2-5 hour trips for specialist, testing, surgeries and it is very reliable and comfortable too. I feel pretty safe in this vehicle vs so many others i have owned. She had never left me broke down or stranded the only issues was the under body being severely rusted most likely due to sitting in grass prior to me getting her. I've had to replace so many parts but that us just part of car ownership. She has less than 80,000 miles and runs like a champ. Her body will take a 💩 due to the reasoning stated above and the engine will still likely be a beast.


If you can find a decent one purchase.

The year is 2022. I'm driving a 2003 Buick century. With 73,000miles. This car has been to 2 mechanic for an oil change and radiator flush. Both of them said the car is in great shape for it's age. One issue is paint peeled off the bumper and of course is out of warranty. This car is my dad's but now belongs to me. Great sturdy dependable car decent gas mileage. Has lot of bells and whistles even had OnStar. You feel like you are in a luxury car
