I own a 1997 SVT Cobra, it has 84,000 miles and I treat this car like a princess. About a week ago I decide to drive it to work instead of my beater and half way there it starts knocking like a son of a bitch. I have no clue why, I do know that its a main bearing that's kamikaze. I would like some advice on how much I could sell the car for in its current state, its all factory interior and body work, it has a bbk cold air intake, kooks long tube headers, slp full cat-back exhaust, and steeda coil overs and anti roll bars. The car is mint, garage kept and fluids changed every 4k miles. It is a five speed car with the original 32v 4.6. I was thinking maybe 5 grand? Let me know what you guys think, if anyone knows why it would spin a main out of nowhere that would be helpful too.
