When it comes to choosing a car, we all have our own preferences as to what we need. It may be that you have a family and often have to transport a full car of people plus need room for luggage / shopping etc, if this is the case then a spacious car will be top of your list. It may be that you have decided you want to get a car that costs you less to run, so a smaller, low emissions and high miles to the gallon vehicle will be the right one for you.
Firstly make a list of what you mostly use the car for then from this list decide what is important. Do your research online to find out the most reliable, economical cars etc. to narrow down your search.
Budget is often another factor, but don’t let be the only basis for your decision on choosing a car as within any budget there are still a number of vehicles available to choose from.
