The Chevette wasn't that bad, apart from rust issues and the fact it was an American Opel Kadett City C hatchback with a redesign. still, glorious T Body GM chassis (same body the Daewoo Maepsy was based on)
the Vega's engine was its worst offender, once you reached 100,000 miles, it was done.
the car itself was ok, although most have v8 swaps now apart the Cosworth model.
