I don't think being concerned that the car might have a breakdown that leads to a serious injury means you should buy a Volvo!
I think we all accept the risks inherent in driving a 3 wheeled (and therefore much less stable) open car, with no roll protection, very little impact protection etc.
From what I can make out, and by your own admission you've not had any of the issues suffered by others but have convinced yourself you MIGHT. Because of this you drive no further than 30miles. Maybe you should reconsider the Volvo...
