Yes, correct, I just laid out $ 5000.00 to fix an ABC issue. I just hit a little bump, like a plastic road reflector that is in the lane divider. I mean it was only an inch or less above the road surface and my front left side sunk. Took it to MB DEALERSHIP and boom $5000.00 to replace left front ABC . Works great now, but who knows when one of the other three will spring a leak. Just be prepared, the ABC is notorious for problems In the older SL’s. Mine an 2004 SL 55 AMG. Just saying he is correct. Save your money for the ABC when it fails, which inevitably it will!
The engine is rock solid and is the best ever, the suspension has its issues!
