Spotted this one, and many others, on the polish site allegro.pl. The 140 series Mercedes seems to be particularly popular with Polish people, and even where I live in Australia, when I bought my C140 in Sydney - the seller was Polish! Anyway, having a look at this one it has reaosnably average mileage for its age and type, and looks overall in good condition. 

The seller at the time noted the following comments about this car, which is a rare 420 model (most are 500/600)..

The car is free of corrosion, except for one small efflorescence at the shaft and one at the wheel arch front. Factory paint outside the left front wheel arch.

Practically perfect condition, with the following work done in the last 12 months:

• rear suspension (new)
• steering gear
• gearbox electronics + oil filter (new)
• flow meter (new)
• whole ignition system replaced (coils, candles, pipes) (new)
• ignition switch (repair - jammed)
• parking sensors (wiring harness worn)
• oil and filter service (valvoline)
• timing tensioner (new)
