I've been driving the Symbioz Full Hybrid with the iconic trim for 3,500 km. I test-drove both cars. I think the win goes to the Symbioz. Good quality at a family-friendly price. Unfortunately the Opel is simply too expensive. Strangely, what never really gets mentioned is that the Symbioz's suspension is absolutely superb.
