The 190e wins in terms of maneuverability. being a C-Class, it's smaller in size vs. the 124 (E-Class). Quite ideal -- specially when used mostly in the Metro.
In terms of interior space comfort, the 124 wins over the 201 (190e). The kids would surely enjoy the space it provides when they go to school.
Maintenance parts for these MB models are available. They may be a little more expensive than Japanese parts you may be accustomed to buying
BUT is proven to last longer. Ergo, when you fix an MB, make sure you use it (and not sell it right after the fix).
It is a known fact that any car (any brand) with age would require more maintenance/TLC. This does not single out MB models. One way you could reduce the risk of getting a "problematic" MB is by acquiring one from which you know the level of maintenance the current owner gives it. Makes sure to bring a reputable/trusted mechanic knowledgeable on MB cars when you see a unit.
Personally, I would go for a 124 260e. It has the space and power to weight ratio is ideal.
Hope this helps and Good luck!
