How many times have you been asked to evaluate a potential car purchase for a non mechanical friend/relative/complete stranger and advise them if they should buy it, only to have them ignore the issues and buy it anyway. I have had this happen numerious times and when I provide my input they ignore my comments and buy it. One relative did this with a stick shift car with 100k miles (they didn't know how to drive a stick). The previous owners could not recall doing any maintenance (oil, brakes or clutch). My relative bought the car and the motor blew up 3 weeks later. I soon realize that when they start trying to justify the purcahse inlight of all the issues, I just wish them the best of luck and tell them I wouldn't buy that car.
