In this age of electronic gizmos and wotsits, deciding what is important and what's not can be a technobabble nightmare. As if the car buying process wasn't difficult enough already.
There's no firm and fixed rule that can be applied to every brand, and putting that into perspective is incredibly important.
A fairly obvious rough guide is that the newer the car, the better the features are going to be.
Whether it's as simple as having an easy connection to your Bluetooth-toting smartphone, or advanced safety features like crash mitigation systems or pedestrian avoidance, they're all going to come in useful at some stage.
Stability control is one of the most important features you can hope to get in a new car. In fact, in many markets it's now compulsory to have ESP on all new vehicles.
