I absolutely agree, the B99 is stunningly beautiful.

But hyperv6 above's right, even tho' Stirling Moss called the E-Jag "the dumb blonde of sports cars."
The last one, the Zagato, is alright. The rest look tortured, trying too hard, compared with either XK or E-Type.
Amen squared and cubed. Conventry was hammered by the Reich. But Jags not as unreliable as many here in the States believe. Much of the problem was simply mechanics unfamiliar with them, and most of those available here suffer from decades of deferred maintenance, owned by people trying to own them on the cheap.
Like many English cars, their cooling systems not meant for much of this continent's heat, but there are easy fixes, not the least of which avoiding antifreeze unless the car sees two consecutive nights of a hard freeze (30 or below), or has AC (stupid in any serious road car), in which case it needs 15% antifreeze even in LA/Phoenix in August to prevent the heater core from freezing.
Straight water and a good rust/corrosion inhibitor like Red Line's or No-Rosion.com all any car otherwise requires.
If Jaguars weren't reliable, British law enforcement wouldn't have used them. Of course, the XK engines in the Le Mans winners were different than those in US sports models, even most of those raced here.
"Grace, Space, and Pace" has to be one of the best slogans since Packard's Ask the Man Who Owns One, MG's "Safety Fast," or
"It's faster by Railton."
