Looking at buying my first Mercedes, what should I know and what to look for?
Yeah, there's no cheap Benz. For a 140, a post-96 S320 is as close to a reliable, low-maintenance daily driver as you will find. I have an m120 coupe, other end of the spectrum.
Rule of thumb is the most perfect, middle of the road Benz (yours is just north of middle of the road - or would that be east?) will cost you an average of maybe $3k a year at retail dealer prices to maintain. You can adjust that gradient according to self-repair, indie shop usage, etc. That's your baseline. Parts are also becoming much harder to find, quickly, on the 140s, at least parts not common to other models - body, trim, interior, in particular. You will pay through the nose even online, if you need a rare, NOS part.
