looming

Hello all, as per the heading I retire officially next March Yeehaa!I have no great plans to fulfill during my retirement so I've turned my attention to my car. I'm well into my 7th year with Mercedes having 1st owned an S211 E220 for 3 years and then I bought Developer's cast off, just kidding...

I have a `99 W220, it doesnt cost that much to keep on the road, the only thing that worries me is the suspension as I have heard horror stories, I normally work on if it aint broke dont fix it, but would anybody recommend replacing the relay which seems to be at fault yearly or so to stop it...
