An identical Z52 setup did the identical for '91 Corsicas, though it killed the LTZ.
Curiosity killed the cat. Sales dwindled thereafter as the two-door was killed after '88 and the mainstay 4-door departed after '89. Not that Chevy needed to worry, for the Celebrity handily surpassed Malibu's peak sales on this decade (278,000 for '80) by averaging 350,000 a 12 months for 1984-87 peaking at practically 405,000 for '86.
Overall, Celebrity was a winner. Inner construction, ch***s, even drivetrains were all the same, however squarer, extra-formal notchback styling contrived to make Celebrity look more expensive than the slopeback Citation -- which it was, by some $1500-$2000.
A Euro-model Corsica known as LTZ arrived for 1989, together with a 4-door hatchback that was hard to tell from the normal notchback. Nobody a lot favored the unique engine -- a new Chevy-built 2.0-liter four with old style overhead-valve head (some known as it the "junkyard engine"

-- and the 4-speed manual transaxle wasn't the slickest around, however that was about it.
Under the hood sat the High-Output model of Oldsmobile's vaunted new 2.3-liter "Quad-4," a real Euro-style twincam engine with 4 valves per cylinder and an excellent 180 bhp.
