Ok so ive been having this problem with my supra ever since i bought it. the car has a newer battery in it so i know its not bad. Well usually after 3-4 days the car doesnt start, as in no gauges or anything, even power door locks dont work, headlight motor goes up VERYYYY slowly. this is with the theft deterrent disarmed. i dont really lock the doors so it doesnt go on. im just curious as to why every 3 days or so the battery seems dead. if anyone would have an answer to that it would be helpful.
