Given its troubled start its a constant source of amazement for me that the XJS managed to soldier on for an incredible 21 years . Imagine that feat happening today , you couldn't . I remember the first one I saw as a child , the mood was very much " is this the replacement for the E Type , surely not ? " and for me personally that thought simply never changed , I never had any desire whatsoever to own one . These Boys in the link above seem to think I got it wrong but I am not persuaded .
I don't think the XJS can be considered a landmark Jaguar, it wasn't really remarkable in anyway. Nothing wrong with it, just not ground breaking or revolutionary. It's like saying something is awesome when it's just quite good. I'd say the XJS was a worthy Jaguar but leave it as that.
