### Instruction: What should I think about when buying a car (summarization)
### Response: There are many aspects to consider when choosing a car. Your budget and your needs of the vehicle (seats, luggage space, ability to drive on rough terrain) are probably the main two. These factors probably then influence how you prioritise between age of the vehicle and the mileage you're willing for it to have covered already, the type of car (convertible, estate, coupe, 4x4/SUV etc.) and the brands you consider desirable. Buying a car is typically somebody's second-largest expense, so proceed with caution; if you're planning on buying a used car, you should thoroughly research its history via online 'vehicle history check' reports and conduct the relevant checks to make sure that the person selling the car is entitled to do so.
