Anastos Motors - Service Center

We bought the car in May of 2011 and immediately I noticed several problems. I contacted Anastos about an engine knock. They said they were too busy and that their "time is too valuable" to sit around noticed several problems. I contacted Anastos about an engine knock. They said they were too busy and that their "time is too valuable" to sit around and listen for a knock that only happened once in a while, while the car was warming up. Just yesterday we brought the car in with a list of things wrong with the car from when we bought it including, lower control arm/ball joint, Speaker not working, air bag sensor for passenger seat not working properly, and engine knock. Along with some problems that appeared such as a noise while breaking (gringing/not the indicator), oil on some hose lines going from the oil pan to the radiator for oil cooling, and a broken clip. They informed me that the speaker is not covered because it is in the door, I'm okay with that one. But now they're saying they do not want to touch anything on the car because the oil is low and dirty. I just changed the oil less then 2000 miles ago, and the oil level 3 days before I brought it in was perfectly fine... I'm smelling a scam. More
