Autozen or PEH: I had my local indie run a compression check on my 300SD a few days ago, values were 25-16-25-25-22 (all in bars). The number two cylinder is on the low end of acceptable/marginal from everything I've read. Aside from some impact on cold starts, how concerned should I be about the difference between the #2 and the other cylinders - does that disparity imply future deterioration?

BTW, my indie said he could get it rebuilt for me; alternatively, if I can live with the cold start issues, I could just change the oil and run it for years.
