Here are some questions to guide your decision:
If you already own a car, look at the deficiencies of your current vehicle.
If the vehicle is used by other members of your household, ask them as well.
This will form a wish list for your next purchase.
Create a priorities worksheet, to help when comparing automobiles objectively. Write down items and a value from 1 to 10 (10 being critical) for each. Do some preliminary research into costs. See what is usually included, and what features are optional. Create an initial budget for the vehicle. Evaluate if it is within your monthly means. Scale back your wish list if necessary.
