Purchased this for my wife with only 20k 4-years ago and the car has been great except the transmission.
The 722.6 transmission was problem in the older E320 and still is.
The TCU connector seal failed which Mercedes had an updated part but then in leaked later on also.
Read some forums and I'm not alone.
Even the new 722.9 Transmissions are having issues.
I have owned 4 Mercedes and all the transmissions have had issues.

This is the ultimate family vehicle and we don't look for a second at suv's or hybrid vans or whatever. Practical, sporty, smooth, clean lines, great ergo, wow wow wow. Bought all the roof bling, rack, bike rack, cargo box from Mercedes-Benz
For 2004, the E-Class wagon benefits from the same full redesign the sedan received last year. A V8-powered version of the wagon is available this year and the 4Matic all-wheel-drive system is optional on both sedans and wagons. Finally, the DVD-based navigation system, which was delayed for 2003, is on the options list this year.
