2005 Buick Park Avenue Full Review
Date Published: 11/23/08
2005 Buick Park Avenue Review
Buick's flagship sedan gets revisions to grille and taillamps for 2005, and the base Park Avenue model gains the front-fender "portholes" previously reserved for the top-line Park Avenue Ultra. Both models have a 3.8-liter V6 and 4-speed automatic transmission. The base model has 205 hp, the Ultra is supercharged for 240 hp. ABS, self-leveling rear suspension, and leather upholstery are standard. So is a front bench seat for 6-passenger capacity; Ultra offers optional front buckets. Ultra has 17-inch wheels, the base model 16s. Standard for Ultra and optional for the base model are a firmer Gran Touring suspension, OnStar assistance, traction/antiskid control, and a tire-pressure monitor. Optional rear obstacle detection and a head-up instrument display are also available. Buick says 2005 is the final model year for Park Avenue's current design, which dates to 1997. It says the final 3000 Park Avenues will be Special Edition models with identifying logos, chrome alloy wheels, and available black-and-platinum exterior.

News
Park Avenue lives on in spirit with the V8 version of the 2006 Lucerne, which ladles new styling and more-upscale appointments on the basic LeSabre/Park Avenue platform. An entry-level 3.8-liter V6 model aims to keep value-minded LeSabre owners in the Buick fold. The costlier, more luxurious V8 Lucerne uses GM's familiar 5.3-liter engine, newly modified for front-wheel drive and featuring GM's fuel-saving Displacement on Demand cylinder-deactivation system. Pontiac's upcoming Grand Prix GXP uses this same V8.

Meantime, GM has shelved its rear-wheel-drive Zeta platform and several new models planned for it, including a V8 Buick flagship sedan positioned upstream of Lucerne. GM eliminated the program as an emergency cost-cutting measure in the face of a severe profit squeeze brought on by slumping sales and the crushing cost of worker health-care benefits.

Pros Cons
Acceleration Fuel economy (supercharged V6)
Passenger and cargo room Steering/handling (base suspension)
Consumer Guide® Road Test Ratings
Acceleration

Base Ultra Class Average
5 6 6.7

Base models have ample power, Ultras are impressively quick. Smooth, alert transmission aids both.
Fuel Economy

Base Ultra Class Average
5 4 4.1

Base test model averaged 19.8 mpg in a city/highway driving mix. Test Ultra averaged 15.3 mpg in mostly city work, 20.3 in mainly highway travel. Buick recommends regular-grade fuel for base model, premium for Ultra.
Ride Quality

Base Ultra Class Average
7 8 8.2

Standard chassis favors comfort over handling; it delivers a cushy ride, but with too much float over dips. Firmer Gran Touring suspension provides better body control without being harsh.
Steering/Handling/Braking

Base Ultra Class Average
4 6 6.8

Mushy, imprecise with standard suspension. Gran Touring suspension reduces body lean, front-end plowing, steering numbness, but not enough to disguise Park Avenue's generous length and weight. Cumbersome turning circle. Available antiskid control works well. Brakes strong, but nosedive pronounced in quick stops, especially with base suspension.
Quietness

Base Ultra Class Average
8 8 8.5

Road noise nicely muffled. Ditto wind rush below 65 mph. Engine just mildly intrusive even in full-throttle acceleration.
Controls

Base Ultra Class Average
7 7 6.2

Gauge layout seems squeezed into dashboard, though available head-up display suits some drivers. Lots of buttons, switches, and not always logically grouped. Oddly, traction-control on/off switch is at tip of transmission shift lever. Cabin decor is old-school Americana, with lots of shiny faux wood. Ultra's plastic center console-bin covers work with embarrassing lack of smoothness.
Room/Comfort/Driver Seating (front)

Base Ultra Class Average
7 8 8.7

Abundant head and leg room on comfortable seats, though standard bench is too narrow for three adults. Available buckets more effective at holding occupants in place. Outboard front safety belts spool out from seat and are thus handy, but not all testers find them a comfortable fit.
Room/Comfort (rear)

Base Ultra Class Average
6 6 8.3

Roomy for two adults and more spacious than in LeSabre, Buick's other large sedan. Still, three's a squeeze, and a slightly firmer cushion would increase long-distance comfort.
Cargo Room

Base Ultra Class Average
6 6 5

More than in most class rivals, enhanced by flat trunk floor and low load lip.
Value within Class

Base Ultra Class Average
7 7 5.7

Park Avenue offers traditional American comfort and amenities at prices that undercut those of other premium large cars. For that, it earns Recommended status--with emphasis on the Ultra model as the better performer and the better value in this line. Continuing slow sales and end-of-line status mean attractive discounts and other incentives should be available.

Pricing Key: Retail prices listed with each report are set by the vehicle's manufacturer. These figures appear on each car's federally mandated window sticker. Most price lists also include dealer-invoice prices. Dealer-invoice prices are what the dealer pays the manufacturer for the car and its factory-installed options. The destination charge is not included in the suggested-retail or dealer-invoice price and must be added to the cost of the vehicle. Car companies change prices frequently throughout the year. If the prices published do not match those on the vehicle's window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

Side Impact, Driver 4
Side Impact, Rear Passenger 4
The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
