I saw the weirdest thing yesterday.
Park next to a car i thought was a 86 or 87 mustang lx.
It said 5.0 on the side but had rs underneath it.
I made my way around the back of it and it said capri.
I was like WHAT THE HECK! I didn't even no ford made 5.0 capris.
Anyway it freaked me out.
Not sure how long Mercury made then, but when the fox body started in 79, Mercury offered basically the same car in the Capri (slightly different body panels and light configurations), including 5.0 versions.
