By JaguarÂ’'s own admission, the S-Type needs a major makeover. And that'Â’s what it'Â’s set to get in January next year when the new XF goes on sale. However, the outgoing model is still good enough to grab 25th place. So where does the XF need to improve? Well, it has to offer greater practicality –– you tell us the S-Type'Â’s cabin is very comfortable, but lacks space and versatility. Lowering running costs would also be a bonus. But maintaining its key strengths on the road is essential.
