The aging Regal is an acceptable car, but nothing special compared with its newer, more advanced competition. Drawbacks include ungainly handling (the optional Gran Touring suspension improves that somewhat) and front seats that become less comfortable the longer you sit in them. On the plus side, the Regal rides well at lower speeds and its cabin is quiet. The transmission shifts smoothly and it's been very reliable.

Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Summary:
General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
What should you do:

Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number.
