Performance is satisfying in basic form--sufficient for most situations--but especially impressive when the engine is supercharged. Acceleration in an Ultra feels much like a small V8, so it makes a strong showing against the 6-cylinder competition. Helped by the automatic transmission's subtle and alert shifting, both models distribute ample, seamless power over a wide range of engine speeds. A base Park Avenue averaged 19.8 mpg using regular-grade fuel, helped by some highway time. Another base model averaged 19.5 mpg with a more even driving mix. Standard steering and suspension settings favor low-effort comfort. Unfortunately, this produces steering that's too light at freeway speeds, as well as floaty body motions over undulating surfaces. The Ultra's suspension is markedly stiffer--possibly too much so for some luxury-car buyers. A Gran Touring suspension setup has been optional on both models. That unit does a fine job of soaking up bumps with little jarring, while maintaining a flat, stable ride. It also quells undue body lean and front-end plowing through corners. Part of that package is magnetic variable-effort steering, which responds quickly with good straightline stability, but feels a bit numb. Braking power feels strong. Simulated emergency stops can produce pronounced nosedive, but with no loss of stability or control. The Ultra, in particular, does a great job of muffling wind, road, and engine noises. Roomy and comfortable, Park Avenue promises space for adults to relax. Head and leg room are abundant. Six-passenger capacity is a bonus, though everyone will be sitting shoulder-to-shoulder when the car is filled. Seats are comfortable, but not sufficiently contoured to give occupants good lateral support when the road turns twisty. Front lap and shoulder belts are anchored to the seat itself, so they move right along with the seats, fore and aft. Belts are handy to grab and always seem to fit just right. Gauges and switches are generous in size, easy to read and operate. A simple dashboard pull-knob operates the headlights. If a secondhand Park Avenue is equipped with OnStar, the buyer will have to pay a monthly service fee to make use of the system. Park Avenues that were test driven when new demonstrated good fit and finish, inside and out. One Ultra driven in subfreezing weather, however, emitted creaks from its suspension when crossing speed bumps or entering driveways.

Value for the Money
What do you get from a Park Avenue? Mainly, traditional American virtues-- roominess, power, and amenities--at a sensible price. This domestic sedan is definitely worth a close look, though some of its virtues can be found in Buick's LeSabre for less money. In addition, it must be said that Buick's customer satisfaction ratings have not been as high as those of some foreign competitors.
