1997 S420 thinking of getting one

[COLDSTART]

I have always been a 124 person and have a few ,I would like to eventually get a 94 e500 when one comes up i can afford, in the meantime i see a few of these 140 bodies and I have an e420 so i would go with a s420, I have a friend at mercedes benz calgary ,parts manager. he said they are great and do not have the expensive issues that the s500-600's have suspension and climate control systems. I am just interested in some feed back for people who have had them or worked on them and make a decision on whether it would be a fit for me and my mechanical ability .Thanks for any feedback .
