that sucks! Though if you plan on driving it long, you would want to get it fixed somewhere, that goes out you might hav a hard time steering the car, could be damgerous.
Get a second opinion! Hav another shop look at it, the stealership could be wrong, you never know.
Especially since you still owe $8k, be hell trading it in and add that to the car price....
Good Luck!
