Where are you located?
That 2.5 liter turbo is an excellent engine. I've driven a 190D with 2.5 turbo power, and I loved it. Seems to be a well regarded power plant.
Sounds like you will do well either way.
When you decide and purchase one of them, you ought to let us know where the other one is. Somebody close might be interested...........
