That’s the SL. More detail here:

Point is - a blanket condemnation (or support) for a particular oil change interval is meaningless without context.
Context like engine design, oil specification, use, and sump capacity. I’m sure there are other considerations, but to just pick a number and argue it is silly unless the other, important, variables are specified.
On the SL, I have no idea how the previous owner drove it. It was bought and owned in SoCal. That helps a lot. I think it was a trophy wife car (cookie crumbs and a yoga brochure found under the seat, tiny scratches under the door handle that line up with a big rock on a ring finger, Kenny G CD found in the player, not a guy’s car, that’s for certain).
If I’m right, it was probably short tripped a lot. Still, given the good oil, port injection, engine build quality, and large sump, a 10,000 mile interval was fine for a short tripped car with those other factors present.
