Character

A28NET 2.8T V6

"Insignia OPC. Same GM HFV6 turbo as Saab 2.8T. Timing chain stretch notorious (chain at rear of engine). Turbo failure. Oil consumption. Expensive to maintain. Great power but fragile long-term."

1.2 NA (Z12XEP)

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