They have, indeed, increased the size of the buildings, Trevor. As recently as a few years ago. The old main halls, including the "red hall" are still in place, whilst the old cafe and shop area is now the Supercar section (including the XJ220) and a couple of small side halls have been added by the old cafe area, including one devoted to the Mini, with a rather clever virtual paint your own Mini item. The Duesenberg still sits in pride of place on the raised dias. There is a nice new foyer area with a good cafe, much enlarged shop and additional exhibition hall off the red hall. Plans are, apparently, afoot to further extend, whilst the restoration and engineering area is way up the back of the site; the test track is still there and used, although my partner says that by the time you have got rolling it's time to stop again if you are doing just one lap......at least that's how it felt in the Wolseley back in the '90s! There is no denying, though, that this is mostly a true museum, unlike the Jaguar Collection at Gaydon which is very much a working collection (except, of course, for the concept cars). Both very much worth a visit (or two, or three!! Well, ok, we have annual passes (via Gift Aid) for both......definitely good value).
Incidentally, back to the photos......the one of the Jurassic coast at West Bay includes the white chalet house on the left which doubled as D.I. Hardy's home in the final series of Broadchurch
The Helyar Arms Hotel in East Coker (near Yeovil) provided a warm and friendly hostelry with ample parking; they must have thought they were hosting a Classic car event as the XK got a valeting each evening!
As always, happy growling
