I own a 1992 400SE (w140) and need some opinions on 560SEC. I owned a 1985 500SEC back in 1992, wish i never sold it. What years are highly regarded on the 560SEC and what should i look for as common issues. Owning a W140 body i have learned what years are peticular with issues, do the W126 have similiar issues with certain years. I am looking to buy a 560SEC or 500SEC. Thanks!
