Hi Julius,
If you just see your car as "Need-one" the koreans aren't the badest one. Those cars got the 7-years warrenty so there might be not that much invest afterwards.
Of course, the 250 kilometers to walldorf perhaps won't be that comfortable and your kids, cats hamsters and mother-in-law might not be that ammused with it, cause of the noise while sitting in there driving around. Ok, beeing a bit silly, but there is always a part of truth included
Back to serious arguments:
The facts are outstanding. The cars are very cheap and a lot of service is included.
The Crashtest-results are now nearly that good, that other cars got, so safety is not a problem and there is just the gap in the comfort.
My personal statement brings me to an audi, but these are really not cheap.
But in the end everybody has to decide personal.
Good luck finding the correct one for you and your family.
