Autonation Greenacres

Autonation Greenacres Damaged my car, and said I could drive my car with a rear end leaking fluid Greenacres, Fl. Florida!!. Took my car in for service and front end alingment. After a 2 hour and 5 mile road test I was givin my car back. I noticed the paint under the drivers door was all scrapped up and the paint missing. Autionation said sorry about that. I also noticed the paper work said rear end leaking fluid, the service advisor said he was meaning to talk to me about that, he also said that it was no big deal and safe to drive . I did not feel safe driving the car this way and contacted GM who in turn contacted the dealer, then the dealer decided that they should look at the rear end and decide what to do. The dealer also told the BBB that all danage was done pre existing, I have an email from the dealership that states other wise. After checking with other mechanic I found out that diving my car for a long period of time could cause the rear end to heat up and the metal parts marry themselfs and in the worst case scenerio myself and family could be killed, and we were traveling to family dinner for Thanksgiving. No reguards for human life what so ever.
