Hi Patrick,

Neither is more important, to be honest. In fact, lots of weight can often make a car less safe, as it has more kinetic energy to disperse in an impact. However, if it’s safety you’re looking for then there are two key things to do. First of all, visit the Euro NCAP website — Euro NCAP is the independent crash test expert organisation and has been carrying out crash tests on most new cars since the nineties. Have a scroll through the results to see which models you like are the safest, but don’t just rely on the star ratings; have a proper read of each result and check out the percentage scores for each type of impact, especially the child occupant safety rating.
