My brother and I looked at a few when he was shopping a couple months ago, test drove a 2007 E350 4-matic with 145k on it. Felt solid as a block, truly amazing car. Also drove a 2002 E320 in mint shape with 135k...also beautiful car. Ended up buying the 2002. Its been great so far, he's put over 3k on it with 0 issues, and it runs/drives fantastic. He's hooked now, I am sure he will eventually upgrade to a 2014 in a few years when you can get nice ones CPO.

We had also test driven a brand new TDI golf....and it was terrible vs. the 02 e-class, especially considering it was 2.5x the price.

Gotta say, the W210 makes the W123 seem like a horse & cart....I would describe it as a "smoother" W126 feel when driving. Its not much different from my 420 which is in mint shape, which helps a lot.
