Another afternoon spent with a stonking thread, thanks to everyone who has contributed :-)
Here is a random selection of transporters of delight from RJC.

Cannot help but feel that BMW were not quite behind the 8 ball when they choose this shabby transporter to carry 6 BMW M1 Procars around Europe, these days BMW dealers will come and pick up your regular 1 series daily driver with a fully curtained transporter for routine service.

ImageShack.us#18, Kenworth, Joe Gibbs Racing, Talladega 26/04/09, with owners permission.
A Kenworth W900L triaxle tractor unit typically has a wheel base between 264 & 320 inches, and will be fitted with either a Caterpillar or Cummins 9 - 15 litre diesel engine of up to 600 hp, mated to an 18 speed O/D gearbox.
Options include radiator sizes of 950, 1200 and 1430 sq inches.
Front axles are rated to 22,000 lbs while the twin rears are rated to 58,000 lbs
The upper deck of the trailer is used to carry the racing cars the lower deck is split to carry parts, tools and a lounge.
The arrival of the NASCAR convoy at a track causes quite a stir see :-

The Iveco Domino HDH Measures 12.41m (40’ 8 ½”) long x 2.55m (8’ 4 4/10”) wide x 3.95m (12’ 11 ½”) tall.
This particular bus is powered by a longitudinal crank end 450hp 10.3 litre/628 cui 6 cylinder Cursor 10 diesel engine.
The Cursor 10 shares in common with NASCAR motors both a cast iron block and cylinder head but the Cursor 10 is way more advanced featuring 4 valves per cylinder and variable geometry turbochargers !
Oh! and it would appear there is room for a Ferrari F2008 in the back.
Next time I go camping at Brands Hatch or Silverstone I want one of these :-)

Of course if you believe, like RJC, that anything that needs a transporter to arrive at the race track is merely an expensive toy you will do as he did and drive your racing car to and from the track yourself :-)
ps is the Gold Leaf Moke and Europa above for real or just a joke ?
