I am thinking of selling my CL600 (this is not a for sale advert)and purchasing a CLS, probably the 500. Several questions for my fellow members. Has the rust problem on Mercedes vehicles (cars) now a thing of the past?, on say a 3 to 4 year old vehicle. Is the CLS a fine vehicle to own? I suppose it depends on what I/you want out of it. There is just me and the Mrs, so size is ok. I tried to get in the rear of one and found it most difficult (I have back problems) the boot is adequate (for most) fuel consumption is not a worry. Comfort is the main thing, and reliability. Thank you in advance.
