Renault Symbioz

The Renault Symbioz feels less like a traditional car and more like a rolling living room that's been told it's allowed to drive — its flowing lines and minimalist cabin are pure concept-car theatre that teases the future of everyday transport. For buyers with an eye for design and a taste for tech-forward ideas, the Symbioz is an alluring vision of what Renault could offer tomorrow, even if it's not yet a model you can park in your driveway.

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.

SEAT Leon

SEAT Leon pairs sharp, modern styling with a cabin that's sensible and slightly sporty, making it an appealing choice for buyers who want flair without fuss. It drives with eager composure and offers a neat balance of comfort and agility, so you get everyday usability with a wink of fun.

Mechanically the car is fairly well built, apart from the rear axle.
The air conditioning is effective and visibility is good, while the FR setup paired with the 18" wheels, in my view, hurts comfort — getting in and out can be awkward. Once on board, though, the seats are very comfortable. The infotainment is comprehensive, with a generously sized screen and full-link smartphone connectivity; the factory sat-nav does what it can, but obviously Maps is superior in every way.
All in all, a fun/sporty car that also winks at family life thanks to a roomy boot and modest fuel consumption.
