Year-to-year changes

• 1998: The Oldsmobile Intrigue was introduced as an all new model. Available in GX (base), GL, and GLS trim, all featured the 3.8 L V6 and 4-speed automatic transmission standard.
• 1999: For the beginning of this model year, the DOHC 3.5 L "Shortstar" engine was standard in the top-line GLS and optional on mid-level GL and base GX models. Early GLS models could be ordered with the 3.8L instead of the standard (for GLS) 3.5 L, but later on the 3.8 L was phased out and the 3.5 L became standard on all models. Decklids now wore a small Oldsmobile badge. In the previous model year, there was a complaint that some people couldn't tell that Intrigues were Oldsmobiles. If you look closely, you can read 'Oldsmobile' molded in the backup light lens in the taillight housing on all model years. All models now got a thicker, leather-wrapped steering wheel. An integrated rear radio antenna was standard this year and after.
• 2000: New wheels featured a fancier six-spoke design. New to the option list for 2000 was an antiskid system called the Precision Control System. Precision Control System was designed to help keep the car on its intended path by selective braking of one or more individual wheels. Though optional on all models, GX buyers had to order optional traction control to get the new antiskid system. Heated power front seats were now standard on GLS models. Standard leather door inserts trim not cloth, Retained accessory power was standard this year. "Oldsmobile" emblem on deck lid is larger than on 1999 models, although some early 2000 models carried the smaller version. A new gold-trim package was also available. New automatic headlights were now standard on all models.
• 2001: On GX models, traction control became standard instead of optional. Premium Leather and Precision Sport option packages were also available for this year. OnStar is now available as an optional feature.
• 2002: GLS models now featured a two-tone interior with sterling accents, as well as standard HomeLink, sunroof, and driver lumbar. All models featured new family of radios with RDS and standard CD player (borrowed from the newly redesigned Aurora). Tropic Teal and Indigo Blue were two new exterior colors. All models had new LATCH (Lower Anchor and Top tether for Children) in three rear seat positions. Sun & Sound package was available on GL models (includes Bose sound system and sunroof). New winchester headliner was inside. Production of the Intrigue ended in June 2002 as part of the phaseout of the Oldsmobile brand. The Final 500 Collectors Edition versions came in a unique Dark Cherry Metallic paint with special classic-style Oldsmobile emblems and featured Aurora-styled 17-inch chrome wheels. Owners also received a special commemorative packet.

Final 500 #499 was the last retail model and was special-ordered by a member of the Southern California Chapter of the Oldsmobile Club of America.

One-Off Variants

• Intrigue Saturday Night Cruiser Concept (1998) - A modified version of the Intrigue that features a body kit, exhaust pipes relocated to the side skirts below the rear passenger doors, custom 6 spoke rims with Oldsmobile logos in the center, and a sunstrip on the windshield with 'Oldsmobile' printed in white text. It is unknown what engine is used in the Intrigue SNC, as next to no information on the car exists. The whereabouts of the Intrigue SNC are unknown.

• Intrigue 442 (1999) - A customized Intrigue wearing a body kit similar in design to the Oldsmobile 442, much like the Alero 442 show cars. It debuted at the 1999 SEMA show. It is painted in Pearl White and Gold for a Hurst style motif. It rides on custom 6 spoke rims. The Intrigue sports 6 Oldsmobile Tilted Rocket logos on its body: two on the front bumper below the turn signal lamps, two on the rear bumper below the corners of the rear fenders, and two small ones on the driver and front passenger doors. These door logos also sport '442' text in a brighter white to contrast against the car's main body color. The logos on the doors are also embroidered into the headrests of the front seats, and is featured prominently on the engine cover. In total, the Intrigue 442 features 9 Tilted Rocket logos (11 if the standard bumper badge and steering wheel logo are counted). On the windshield is a sunstrip with 'GM SEMA PROTOTYPE THE LAST OLDS 442 BUILT' printed in white text. It is powered by a 550hp Cadillac Northstar V8. The Intrigue 442 was sold at the Barrett-Jackson Scottsdale 2009 auction, and again at the Mecum Auction in 2022.

• Intrigue OSV (1999) - A custom Intrigue created as part of "Oldsmobile Specialty Vehicles", an experiment in an aftermarket tuning brand for Oldsmobile. It debuted at the 1999 SEMA show. It features an Eaton supercharger fitted to its engine, raising its horsepower to 260, 13" cross drilled Brembo brakes hidden behind custom 19" RH Evolution C6 wheels with Oldsmobile center caps and fitted with Michelin Pilot XGT Z4 tires, Koni oilover struts and springs, Borla center exit exhausts, an aggressive body kit, and OSV fender badges, and is painted in a special cherry red paint, like the OSV Alero and OSV Silhouette.

• Intrigue OSV II (2000) - Another Intrigue modified for OSV, this time painted in dark green. Little information exists on the Intrigue OSV II, but it appears largely the same as the 1999 Intrigue OSV. It is part of a second batch of OSVs alongside the Alero OSV II, and Silhouette OSV II. The engine used in this version of the Intrigue is the same V8 engine that came from the Aurora.^[5] The whereabouts of this OSV Intrigue are unknown.
