Rick,

The 140 is a very well rounded car.....however it is very complicated and thus the expense to repair can be rather extreme
If you are looking at diesel ..look very careful at the history and have it checked out by an MB....even a non-diesel car should be checked out ESPECIALLY AC components as this can cost you thousands......also check all electrical items...closing assist,window regulators etc.....
and DO BUY the extended warranty if there is one available....this is a car where you have almost a 100% guarantee of recouping the monies for the extended service
Also you will probably want to look at cars with long detailed service history...the premium you pay will serve you well

All that being said I think you will find the 140 to be one of the most sophiticated autos on the road....great looking in and out

happy hunting
