 My first W140 experience was with the first year, 1992 600 SEL with 72K miles in perfect condition. I put 5,000 miles on it over 3 years and had $8000 in repairs! Avoid the early years! As of 6/2011 I decided to give the last year model (1999 S600 with 48K miles) another chance because of my fondness of this body style and incredible interior. Took in for basic oil change/tranny service. Back window bracket broke at $425 and another $1200 in adaptive dampening system. A beautiful and awesome car, powerful, incredible options but only great as a "Sunday driver" as they are just not dependable and extremely expensive to repair and maintain. So it is a "Love/Hate" relationship. 400 miles added
