Im sorry things are going so bad for you. I feel ya knockin. I've only had one bad experience with my car. I used to own a 1997 Toyota Supra Limited edition (nice ass car) and my ex (who i almost killed for this) shut her garage door on it...and put a dent in it....( i almost cryed!

ahhhh)...and when I took it to the body shop to get it pulled, they told me to come back tomorrow. When I came back...there were three major problems here...
#1. I had less than a half a tank of gas and I had a full one when I dropped it off! This means they drove my car! and i dont mean down the street!
#2. The Dent wasn't even touched...wasn't pulled...probobly wasn't even looked at...
and #.3 They wanted me to pay $150.
I bitched and moaned about it and they gave me the runnaround so i just said...i'll just be back tomorrow.....WITH MY ATTORNY! yep...they fixed it for free and even offered to give my engine a tune up (which i declined...seeing as how i wanted them to touch my car as little as possible) so you've gotta watch those freaks! People...take note of your odometer when you take your car somewhere! No joke!
