You might check Consumer Reports at the library. The reports aren’t as reliable as they used to be w/reference to home appliances because, according to our repair persons, the appliances are constructed w/built-in obsolescence that’s even shorter than it used to be. Not certain re: automotive. However, you might be interested in checking NHTSA (National Highway Traffic Safety) for information on recalls for specific brands and models.
Already did. There were more service bulletins for the Golf than the Mini.
Before I purchase a car I like to find one in traffic and give it a good, solid rear-ending. You gotta know if it can protect you from the idiots on the road.
I try to follow-up with the driver after about a month to see how he/she is holding up. One good way to make sure they tell you is to hold off on the insurance settlement.
