My brother bought and restored a used car for his oldest step-son, who managed to total it within 24 hours. Brother said nothing, but the next time that step-son and mother had an argument, step-son's suitcase came sailing into the room..... Message got across loud and clear. Take the car, keep a log and stop whining! It may be a wreck but it's free. Besides, it has to be certified before you cn drive it. Get Dad to check on the price of getting it done, and then sit down with him and see if it's worthwhile or you should be looking at another used car. Remember the golden rule: those with the gold make the rules. Dad has the gold, you don't. Wanna make the rules. Simple: get a job, move out and then buy what you want. Oh yeah, make sure that Dear Old Dad does NOT include you under his insurance policy.
