I'll let John speak for himself;
This was my old p&j
1959 XK150 which I owned for 5 years. As 1560 said did like to leak a lot and in the rain a coat and umbrella were recommended. Great car and went like stink considering it was 50 years old.
The Jag lot and I'll limit to the XK crew weren't as friendly as the Morgan bunch, that may have been an age thing as I certainly wasn't your typical XK owner. One of the XK clubs was always running event the downside was I'd have needed to be the dictator of a large African nation to have afforded any of them.
Must admit though that I wasn't called flamboyant by any of my fellow Jaguar owners so I may have to send the Mog back
The posted picture of the XK doesn't look right as is seems to have features of both an XK120 and an XK140, side lights, bumpers, chrome all mix a match. I'm sure someone will provide a conclusive answer to the question.

I'll see if I can find any of my old XK books.
