Nice Pagoda. If I recall correctly, early Euro 280s had a hotter camshaft which gave a few more hp in the higher RPMs.
Yes, those are definitely 230SL wheels/caps, but no big deal. Can be replaced, as you say.
What might help with the sale is stating if you have maintenance and repair records that support and document the low milage (kilometerage?). A car with only about 60,000 miles could be a big deal for some people.
A few more pics would help generate interest, but also maybe draw criticism? For some reason, some people enjoy "picking apart" cars for sale. They know historically correct, and simply wrong or damaged stuff, when thet see it and need to comment. Hopefully you have a lot of pics stored online and can share a simple link here, or just to interested parties.
