I'm not sure a shed would be quite good enough as a home for a Daimler Dart. Here in UK a shed is where we keep inconsequential items like old flower pots, broken garden furniture and useful (but never to be used) lengths of wood.
I know someone who runs one. One thing he's told me is that they suffer form quite serious differential problems. Usually the long-term fix is a conversion to a unit from a different vehicle as reconditioning or replacement of the original is fiercely expensive and some of the bits are scarce. Although a permanent remedy, the conversion isn't cheap in its own right. If you're seriously considering one it may be something to be aware of/factor in as a possible extra cost after purchase. Other than the troubles he's had in that area, the chap I know seems to very much enjoy his, and it's a pretty car.
Compared to other contemporary British sports cars the SP250 looked quite outrageous with its tail fins and wide front grille. Power came from a powerful 2.5 litre V8 which gave the car a top speed of 120mph, the Police were quick to spot the cars potential for use as a high speed traffic car and many saw service in this role.
The most curious thing is the fact that the headlights, front blinkers and gauges, to name a few, were interchangeable with the austin/morris mini, wolseley, triumph, or anything british from the sixties
