Character

1.6 SIDI Turbo A16XHT/A16SHT/B16SHT (MGE)

"GM Medium Gasoline Engine: direct injection, chain-driven, 170 PS (A16XHT) or 200 PS (A16SHT/B16SHT) in Astra J/K, Insignia A/B, Cascada, Zafira Tourer. German used-car guides list no known engine problems; watch intake carbon and oil consumption, and avoid high-mileage automatics. Evidence base is still thin."

1.2 NA (Z12XEP)

"Greek city car workhorse. Simple, cheap, 200k+ km proven. Chain tensioner is the one known weakness. Bulletproof otherwise."
