Need advice about purchasing car

Is the only parameter to guide your decision a financial one? Do you like the car? Does it fit you current and forseeable future needs? Maybe your family gets bigger. Is the avialibility of more modern safety and comfort features any value to you. Do you like the idea of driving a vehicle with low miles attractive to you? How comfortable are you with a road trip with this car? Maybe a car with the features I have mentioned is out of you budjet but not all decisions are finiancial
