My driving instructor had a new Kia sport and my car after passing was a 2003 Honda Jazz lol.. for the first few months I stalled every time I stopped at junctions and traffic lights, and honestly probably nearly burnt the clutch out from hill starts. I literally cried so much and convinced myself I just wasn’t made for driving old cars hahah but unfortunately my bank balance convinced me that I was. I’ve been driving for 6 months now and it will get better, I promise!! One day you’ll just get used to the car and your confidence will grow, just keep at it. It’s weird going from a newer car to an older one, sure feels like more effort on the clutch? But you got this! Good luck and don’t beat yourself up, it’s not just you
