That's a bit harsh. The E63 near Maidstone mentioned earlier would have been a great contender (as I understand) had it had the correct 'must have' toys inside and pano roof. So cars in good condition do exist, but with the options wanted by the OP, it narrows the field down quite a lot without having to go and look at the car.
I was looking for a s/w211 E320 CDI for the best part of a year, and virtually none came up with the options I wanted, which was simply heated seats, the later NTG2.5 COMAND, and if possible real leather.
I was very surprised at how many DIDN'T have heated seats, and the ones that did I initially dismissed on what appeared to be rough condition in photos (I mean rough, not just that they weren't perfect).
I then thought I should be less picky and look at the cars that looked a bit tired on the photos, but might have been okay and need only a little work to sort out. Complete sheds, every single one of them. Rusting tailgates by the wiper arm, rusting arches, broken interior trim, dodgy sounds under the engine, random tyres on all 4 corners. I did find a couple the met the bill without the COMAND NTG2.5, but at the time that wasn't a compromise I was willing to make (seeing as I only had 2 firm requirements and on the face of it neither of those seemed particularly outlandish).
In the end, I had to go for the w212 as they were more plentiful.
