Audi A3 Sportback

The Audi A3 Sportback wraps premium materials and crisp German design into a practical hatchback package that makes daily driving feel smart rather than showy. It’s nimble in the city, composed on longer trips, and carries just enough swagger to satisfy buyers who want quality without shouting about it.

It's an easy buy for shoppers who want smart packaging, tidy handling and a dash of personality without fuss — a sensible little crossover that makes everyday driving a bit more enjoyable.

Definitely the Hyundai Bayon — the most important thing is the simply designed 1.2 MPI four-cylinder engine, 84 hp, adapted for LPG and cheap to repair, beautiful looks, a five-year warranty, cheaper to buy, and performance completely sufficient for a senior. A four-cylinder engine runs smoother and is better refined. I will buy this car in December 2026 at the Hyundai dealership in Toruń.

I bought the HUNDAY BAYON one month ago.
600 km later, first small problem — the gauge stopped working.
I have an appointment set for 15 days from now. That said, it’s a real pleasure to drive: very smooth, lively acceleration, comfortable and perfect visibility. 800 km on the clock, but I’ve noticed city fuel consumption is much higher than advertised — 9.7 litres/100 km, mostly urban driving.
