That Pontiac LeMans was an Opel Kadet built by Daewoo in Korea. That was not a particularly good time for Korean cars, and Daewoo in particular was the worst of them. Complete and utter crap.
The Chevy Sprint/Pontiac Firefly (nee Suzuki Forsa - or was it “Swift” originally?) was OK for what it was, a very basic 3-cylinder fuel-efficient commuter. However, GM was still selling a 3-cylinder version of it after Suzuki had moved on to a 4-cylinder for their version. As usual with these things, the Suzuki version was built better.
Any reason why the US version was built in South Korea by Daiwoo of all companies? The Europeans were smart enough to have their version built competenty. I think the European version won Motor Trend car of the year and other awards a for a few years. The Pontiac version wasdefinately not the same as the Opel.
