i agree with sudheer, you never know when you'll need money. better off shelling off a small amount of a reliable but decent vehicle and saving the rest for something practical. a 25K car will cost you quite a bit for upkeep(oil changes, tires, routine maintence)/gas/insurance which should be very high for a 17 year old/raised insurance after an accident(very likely no matter what you say now)/repairs, etc. not worth the work effort unless you have much higher wages then i'm guessing.
