I've been driving the VW T‑Roc for a few months now and I'm totally satisfied. 🚗 The higher seating position gives me a great feeling of security and the visibility in city traffic is excellent. I especially like the modern infotainment system — everything works intuitively and quickly. On the motorway it feels very calm and stable, even at higher speeds. Overall a great car that's a lot of fun and still economical.
