A frequently-asked question is (in essence) "hey, I just found a 210, should I buy it?" Quite often these questions come from those who are not familiar with MB and indeed, this might be their first MB. So I thought it might be useful to put together a laundry list of issues that are relatively common -- or at least things that should be carefully examined, preferably by someone who knows what they are doing.
I'm sure I've missed something, so feel free to add to the list, but remember the idea is to include things that several folks have seen, not just one or two.
If this works well we'll add it to the "tips and tricks" sticky.
AT gasket, mileage w/o changing filter/fluid
Catalytic Converters (noisy)
Console Pixels
Corrosion in rear seat pan (battery)
Differential Oil Leak
Groaning/Moaning Steering
Harmonic Balancer (recall)
Motor Mounts
Rear Bulb sockets
Rear Main Seal (V8)
Rear Window Regulators
Rust at exhaust hangers
Rust - Body
Seat Heater elements
Sensor, CPS
Sensor, MAF
Sensor, O2
Serpentine Belt Tensioner
Spring Perches (non 4-Matic sedans)
Sunroof
And of course it's important to have maintenance records reflecting regular fluid changes with proper fluids

Mine pre-2000 W210 never had most of that stuff installed. Maybe splitting it on different years would make more sense. Why should I worry about pixels on car, that doesn't have the display?
Some might add muffler shine
