This has more to do with Wives than low power.
My wife almost had me committed when I bought my 300 E with 192K miles on it. She thought I had completely lost it!! When I brought it home and began to clean it up (it wasn't bad but had other people's crumbs in the upholstery) she just crossed her arms and patted her foot. After about an hour of wash/polish/wax/ I look up and see her with a Q-Tip detailing the trunk star and the 300E badge!! She had a brand new Mazda Millennia but insisted we take the MB when traveling!!. There's just something about that three pointed star:p
