According to bar.ca.gov, the specific Marathon in this image is a 1979, just FYI.

Love it. I can help you out with engine names later?

By the way: I think you are adding horsepower figures in ps instead of hp, so they don't match with the American amounts.
Ex. Diesel should be 125hp instead of 127hp.

By the way, why 77-82? What changed in 1977?

Different steering wheel and wipers that are moving different were introduced in 1978 model year. I added PS power cause it match KW, but I will change it :)
Of course you can change the engine names so they are proper, mine are just placeholders :)

Okay great, I don't know if those minor changes are enough for this car to have a seperate page from earlier versions, but we'll keep it for now. I understand it's a difficult car.

In the worst scenario we can always copy engines from 1974-1977 model to this page. Also it would be cool to add Medicar, but I am not sure if all engines were available for it.

After I saw the amount of variants listed on automobile-catalog for year 1963 alone, I am for separating Marathons at least to 1963-1974 and 1974-1982, because one page would became quickly a mess.

Are they seperated between consumer and taxi versions? Because I don't think you have to add the taxi versions (or ambulance, other commercial purpose versions).

Those on automobile catalog should be all civilian variants due to A12 chassis code. A11 was used for cabs.

Okay, a split in 1974 is good then, as the bumper changed the most in that year.
