wolf_walker whats wrong with the new ones? I don't know much about the W123 but the W126's are no bargin. They all have stupid little problems, W126, W140, W220. I like them all and hope to move on up threw them as I can afford too. I will always have a W126 but just because the W220's are different doesn't mean there cheaper. I just spent a day with an S430 and it is a worthy successor to my car, fast, looks awsome, expensive. It doesn't leak oil yet, but like any proper MB I'm sure it will soon.
The W140 S600 is nicer than my W126, I can see how they improved the ergonomics and the interior.
