In 2007, the nameplate was revived on a large Buick sedan built by Shanghai GM for the Chinese market based on the Holden Caprice from the WM/WN range.

The Ultra was an upgrade to the Electra Park Avenue trim and featured a standard leather interior with dual 20-way power front seats designed and manufactured by Lear Siegler and styled by Giorgetto Giugiaro of Italdesign; lower-body accent exterior paint treatment; distinctive thick-padded french-seamed vinyl top with limousine-style rear-window surround (available only on Ultra); simulated burled elm trim on the doors and instrument panel; unique aluminum wheels; anti-lock brakes; chromed B-pillar moldings; specific grille and tail lamps; leather-wrapped steering wheel; electronic instrumentation; padded glove-compartment door and unique interior door panel trim.

Inside the Essence was a wide, sweeping instrument panel that housed a prototype Delco Navicar navigation system among other innovations.

This generation featured DynaRide, a deflected-disc strut valving system which first appeared as standard on the Electra, LeSabre, Riviera, and Skylark in 1988.

The Park Avenue was available in Europe from 1991 until 1996 and varied from the North American version by featuring a truncated taillamps with separate amber turn signal indicators and red brake lamps, wider numberplate bezel, fitment of rear red fog lamps, headlamps with different lens pattern, white front side running markers, amber front turn signal indicators, side turn signal repeaters, "flagpole" external rear-view mirrors (mirrors on US version are fixed and do not turn), different door handles, some with a badge mounted directly to the hood rather than an ornament, stronger seat belt and anchors, "softer" air bags, metric speedometer and gauges.

The base trim featured a hood ornament while the Ultra had a less conspicuous tri-shield inset on the upper edge of the grille.

For 2003, trademark Buick "Ventiports" returned on the Park Avenue Ultra along with a bolder grille that carried a larger monochromatic tri-shield badge in the center.

For 2005, the final model year in North America, base Park Avenues received a revised grille, and the previously Ultra-exclusive Ventiports.

Also, the rear fascia was updated across the model line with a prominent chrome bar above the license plate holder with an embossed Park Avenue script and amber turn signal flashers.

The last 3,000 of 7,000 Park Avenues carried Special Edition badging that featured the namesake script underneath a silhouette of the New York City skyline.

In April 2007, General Motors reintroduced the Park Avenue nameplate in China on a luxury sedan that replaced the Buick Royaum.

[24] It is offered in five trim levels: 舒适型 (Comfort), 精英型 (Elite), 豪华型 (Luxury - 2.8 only), 旗舰型 (Flagship) and 旗舰版 (Ultimate - 2010 only) The Park Avenue was powered by Australian-built versions of the GM High Feature engine.

A version of the car did eventually see release in the US market as the stripped down, rebadged Chevrolet Caprice PPV (Police Patrol Vehicle).
