I really wouldn't worry one bit about 190k vs 155k miles.

If we were talking about 54k vs 254k, that would be quite different. Once they're over 150k I treat VDO odos as a suggestion anyway.

I bought my 300SD with 226k showing; if someone were to prove that it actually had 241k I wouldn't have been upset. I don't really see how it affects the material value to any notable extent.
