My '91 300-SEL has been with me since '97 - has the M103 motor - just a slightly larger displacement for that size car. Be it 2.6 liter or 3.0 liter - both are the same as far as I am concerned with regards to maint. and upkeep, etc.
The M103 is reliable, but can become an oil consumer for a number of reasons. Fairly simple to maintain as MBs go. I would imagine the 190E to be the same.
Just my 2 cents.

No argument with anything here. I know the M103 oil idiosyncracies from my '88 300CE.
This from Wiki.
1987 marked the arrival of the first inline-six equipped 190, the 190E 2.6. Fitted with the M103.940 engine, the 190E 2.6 provided 160 hp (119 kW) with a catalyst and 164 hp (122 kW) without. In the North American market, the 190E 2.6 was sold until 1993, the end of the W201 chassis's production. From 1992-1993 the 2.6 was available as a special "Sportline" model, with an upgraded suspension and interior.[6] The
190E 2.3 was sold until 1988, then went on a brief hiatus until it
was sold again from 1991 until 1993.
