One of my comments would be; what has been replaced at 164K miles, for what you are paying?

I would opt for a one-owner, with closer to 100K miles on it, with complete records, etc. but that's just me.

My '99 E300 with 121K miles I bought new and garaged it's entire life, has a full list of items replaced/records, for instance.

I would be wary of any car with incomplete/no records, unless it was close to perfect condition.
