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.
