I have two, XB 302 and XD 5.8.
I had several of both types in my youth in the 1980s and considered both wonderful drive cars.
I dunno, something about the 302 in the XB still brings back memories of a nice balanced car with enough performance.
The XD 5.8 was one of those cars you could get into and be confident, it had enough punch to make overtaking trucks fairly safe.
