Hmmm....8.0:1 compression, perfect for a set of turbos! j/k I seem to remember hearing a blurb about some Asian company using W124 chassis and many other corporate parts to build a car for the Asian market. I don't remember much more and I have not heard anything more until your post.
Importing any non-federalized car for on road use (non-racing) will be a headache by itself. Once you have it here you may have some difficulties getting it serviced anywhere. If you were a Benzmac wanting to build a turbo E-class, then it might not be too bad. j/k Beyond the two problems I listed above, I can't really say much more. Do you have any other information on these cars?
