W126's are great cars and very simple to work on, just buy the best one you can find! Money spent up front on a car with a complete service history, a few owners, no accidents and stories is money very well spent. Also the 560's have the self leveling rear suspension get that checked. Take any car your thinking about buying to a dealer or a shop that knows these cars for a ppi. They cost about $200 and worth every penny. Also mileage at this age isn't very important service history is!

MB's are fun cars but ask yourself this; in the first year will you be willing to put $2k-$3k into if need be? Figure $1,500 for the timing chain $500 to change all of the filters and fluids and deal with the usual old car problems.
