My air hasn't worked since I got me car, does not need freon, the guy said, 'it beeped 5 times and it may be some kind of relay'... Also need to replace my rear air suspension. If I don't leave the raise button on; in the morning the right rear looks like a low rider. I love the car and it also drops out gear when i am on the gas then let off quickly instead of gradually, and will not go back in until I stop and put it in park; then it will be okay. if I am shifting manually it is okay. Is this car worth keeping?
