Expensive. Depends on your driving record, criminal record, credit, etc.

in most states, you cannot buy a vehicle until you are 18. you can provide the money, but it would have to be in a parent’s name. as for the cost of insurance, it depends on the make and model and year of the vehicle. a newer vehicle will be more expensive due to the additional coverages you would want such as comprehensive and collision as well as liability. if an older vehicle, it may be too expensive to purchase collision and/or comprehensive so you would just get liability. rates will vary from company to company with some being cheaper than others. also, if you have drivers education you can get a discount on liability, as well as for drug education, and multi-car discounts on your parent’s insurance.
rather than buying a seperate policy, get it on your parents policy and you will be rated on their vehicle so you can drive it as well, though you inform the insurance company that you have a seperate vehicle that you will drive.
don’t buy a car just to learn to be a better driver, but so you will have your own car. driving it will give you the advantage of getting more experience as well as provide you seperate transportation.

If it is an old vehicle then it shouldn’t cost too much. Try getting a quote online. I am paying less than ½ of what I was before.
