I think a compression rate between 150 PSI and 160 PSI is pretty darn on good for any vehicle. The main thing you want to look for is, not that you have one cylinder with 150 PSi and an other one with 80.
My 1980 model 450SL has 130,000 miles on it and the compression is between 155 PSI and 168 PSI.
