I put my. Bernina in a bernina trolley bag. Vibration no trouble. Then one day the trolley was in the boot of my car when I did an emergency stop ( I could have run over boy rushing out of a side street without looking) when I got to class and took my machine out of the trolley the back had been pushed over the top. Luckily a local shop had a handy man who put it right. Since then my machine travels behind the drivers seat and is far more secure than in the boot.
