I bought a car, sold "as is", because the dealership advertised the car saying "everything under the hood is in perfect working condition. " this was my first time buying a car and they took advantage of it. The car is missing 2 lug nuts on the front driver side, and back passenger side wheel(I don't know how the car passed inspection) it was sold to me with no transmission fluid, when I put some in it began to leak badly(I have pictures) the very next day after purchasing the car I noticed a knocking noise in the engine and everytime I started the car it began to shake for about 10 seconds. Everyday the cars engine would make new noises, by day four the car wouldn't start. Day five it started up but it was overheating within 5 minutes of being on(I didn't know how to read the hot/cold gauge yet being that this was my first car) I tried taking it back but the dealership will not take it back. I took it to a mechanic, they said the transmission is leaking severly, the head gasket is overheating and its warped 4. 0. . Its missing lug nuts, the brakes are bad, and has moisture in the oil. I stopped driving the car unless it was a emergency and while I was on the freeway oneday, the car began to shake violently and started to jump back n forth and I couldn't press the gas because it would not go. I could have been killed on the freeway. I just recently took it to another mechanic shop called arrow's transmission. They declared the entire engine a total fail and unsafe.
Recently (07/10/10) my car just made a loud knocking noise blew a big smoke on the highway at 65mph--the fire men and police that showed up believe it threw a rod because it leaked oil everywhere,had the oil changed exactly 5 days prior.
