2005 Buick LaCrosse review: Our expert's take

By Mark Glover

The Century is history, and the Regal has been retired … So, if you want a new Buick midsize sedan, LaCrosse is your game. Buick’s all-new 2005 LaCrosse is nothing like the rough-and-tumble game played by racket-wielding, helmet-wearing players on an open field. From bumper to bumper, Buick’s LaCrosse is softer, kinder and gentler.

And after a week of driving the CXS, which is the top-of-the-heap LaCrosse of three trim levels offered, I’d say it’s better than the old Buick Century and Regal it replaced.

Let’s start with styling. The Centuryoften was criticized as too vanilla-looking, and the Regal’s edgy looks came off as too over-the-top for some. By comparison, the LaCrosse looks like a happy compromise between the two extremes. A bold, oval-shaped grille is decidedly Buick, but the shape starts rounding off at the LaCrosse headlamps. Fit and finish on the tester were superb, and a practical-size trunklid opened up on a surprisingly roomy trunk – 16 cubic feet. OK, that’s not the 21.2-cubic-foot cavern in the back of the 2005 Ford Five Hundred, but the LaCrosse can comfortably handle the baggage of typical midsize passenger car buyers.

Because the car wears a Buick badge, you expect a certain level of class and sophistication when you step inside, and you get that with the LaCrosse. The tester had standard leather seating surfaces, a tilt/telescoping steering wheel, dual-zone climate control and a six-speaker audio system that more than filled the cabin with quality sound.

Those shiny, 17-inch wheels with the Buick logo in the center looked pretty sharp, too.

The CXS also had attractive wood trim appointments and a center stack of controls that could be mastered in minutes. The tester was a five-seater, but Buick is touting the availability of six-seat occupancy in its LaCrosse.

Maybe it works for some, but I had real trouble picturing six adults compressed in the LaCrosse cabin. Better make sure everyone really likes each other if you go the six-passenger route.

The CXS was dressed up with a somewhat gaudy package of options that included steering wheel-mounted audio/climate controls, power mirrors (with heat and folding capability), a power sunroof and XM Satellite Radio. All this added nearly $5,000 to the window sticker’s bottom line.

As much as I love XM satellite radio, I asked myself if I could still like this car without all the extra goodies. Yes, I could … especially given its surprising performance characteristics.

The LaCrosse CXS gets the smaller but more powerful 3.6-liter V-6 engine with 240 horsepower. (The less-costly CX and CXL come with a standard 3.8-liter V-6 with 200 horses).

The 3.6-liter, all-aluminum power plant gets its extra bite from variable valve timing and a dual-overhead-cam arrangement. It has good pop, but the surprise comes with big-time torque at low revs – an advertised 225 foot-pounds coming in at 2,000 revolutions per minute.

I did not expect this kind of low-end muscle from a Buick midsize sedan, but I quickly got used to slipping into traffic holes on the freeway and easily clearing surface-street traffic when stoplights beamed green.

So, who lied about the gas mileage? And I mean that in a good way.

The fuel economy numbers on the LaCrosse sticker read 19 miles per gallon in city driving and 27 mpg on the highway. For reasons that remain a mystery, I was getting 3 mpg better than both of those numbers.

The federal government has been taking a lot of heat on several fronts for conducting outdated fuel economy testing and releasing allegedly inflated gas-mileage numbers. But, at least in the LaCrosse I drove, the numbers went the other way. Go figure.

Oh, Buick goes on and on about construction technology and building materials that bounce noise away from the passenger cabin. Acoustic insulation was not one of my strong classes in college, but the LaCrosse did roll along quite quietly.

Here’s a gripe that won’t go away: If I had been the king of Buick, I would have equipped LaCrosse with a five-speed automatic gearbox instead of the four-speed, the better to enjoy the advantages of that robust, 240-horsepower V-6 engine.

So, it boils down to whether to drop $25,000 to $30,000 on a General Motors Corp. midsize sedan when there are so many tempting, full-size passenger cars out there for only a few dollars more.

That’s a tough call … and a personal one. But the LaCrosse definitely deserves at least a test drive in any passenger car shopping expedition. You might be pleasantly surprised that less adds up to more.

That’s the appeal of the new LaCrosse – understated in so many of the right places, but aggressive in performance and handling.

Very reliable car

I currently still drive my 2005 Buick Lacrosse CXL. I currently have 145,000 miles on it. Car is mechanically sound given the high mileage I've put on it. The only major downfalls are the ABS wheel speed sensors and HUB assembly as well as the engine coolant leaks at the intake...which I will be doing next. I've replaced the front and rear HUB assembly. I do all the repairs on my car as well as break jobs. Over all I must say this car is very dependable. Remember to get the transmission fluid changed and flushed twice as often when you have high mileage. Remember to put your car in neutral when at stop lights as this will greatly lengthen the life of your transmission...especially with this car.


very reliable. Bought it 10 years ago on the used

Car has alot of miles on it and it is still reliable to for my husband to drive back and forth to the DFW area.
