I think the book labor for that job on the W140 is about 30 hours, and lots of Mercedes dealers want $100 an hour or more for labor, so it gets expensive.

The running job is that the W140 evaps, were hung from a string, and the entire car was built around them.

I saw a W140 sedan undergoing such a job at Smothers MB in Santa Rosa, Calif., many years, ago with the dashboard and front seats removed for the job, it looked like a horror, (have you read any Kafka lately?)

Back in 1996, not knowking about any of this, I was thinking of a 1991 560SEC W126, or a 1992 320SE W140, both of which could be had for about $35-$37 k at the Southern California MB dealers where I was looking.

Not knowing anything, my "gut instinct" told me to go for the '91 SEC instead. Looking back today, I feel lucky I did.
