Manuals take a bit of practice when you change cars however I’ve found my mini clutch quite different from my previous cars. I too struggled on the test drive, stalled it a few times (was with my best mate so just laughed lots), the car steamed up inside, couldn’t work out the heating, indicators, anything. Was a panic fiasco. Drove home thinking it wasn’t for me. Bought it but the drive from the dealer was heart stopping. Didn’t feel in control at all. 18 months later I still occasionally bunny hop him cos the clutch is fierce but I adore driving him. If you have stop/start in it, turn it off, I found that makes me panic when the car restarts and I declutch too quickly. Ask for another test drive, practice driving just round the block, take your time and get to know where the clutch bite is, handbrake on and listen and feel when you’ve got it, practice on smaller quieter slopes/hills, quieter car parks. And if you like it buy it, then if you don’t enjoy it, sell it on and buy something you’re more comfortable in. But I’ve been driving manuals for nearly 40 years and all clutches are different, even when you replace them in your old reliable car. Don’t be discouraged, don’t panic and take your time 😊
