I know that I am biased, but I would definitely go for the diesel (since high mileage with a petrol in the Netherlands will obligate me to sell the cars that I do not use to be able to buy the needed gasoline).
The diesel engines of mercedes run a lot smoother and constant as the petrol engines and service costs of a diesel are (generally) lower.
Why would you consider to sell the 1985 300D, you can do the high mileage road trips with that car as well (I presume).
