2006 c 55 please help me out
Of particular importance (and expense) on these cars is the ABC Suspension system, you will want to stay on top of maintenance for that. It's a fantastic system but it is unique, complex and costly to repair.
Any Merc is relatively more expensive to maintain and repair. It's part of the price of admission for these cars. Still I wouldn't change a thing, I love my CL. I have the older model without the supercharged engine. It has tons of power, I can't imagine an '03-'06 with the blown V8, or God help me a twin-turbo V12. Just can't imagine. But I want one lol.
Grats on your CL!
