tony, car lots kill batteries and let air out of tires automatically!!! we replace about 3 batteries a week and are constantly adding air to our tires. i do not know where the air goes but it does. confused if the cars just sit, air leaves and batteries die. if it is a cheap battery, they usually do not come back to a full charge. replacement time mad if the contour has been there 60 to 90 days, he is about to take it to auction. now is the time to make your 3000 dollar offer or better yet, offer 2700. he just may take it. wink i would laugh
