Yet, I have the odd classic car too, which are tax exempt, and now MOT exempt, which kind of makes up for it a bit...... 
Gotta fill all that empty space in Lancashire with something, eh?
(I have a fair bit of space here, but still don't think I'd get away with having five+ cars
)
One of the reasons I went for this house in the early 90's was that (besides liking it!) it had a massive back garden which wasn't overlooked, and due to a bypass about 50m away over a field at the rear, wasn't likely to be built on either.
I ended up with a decent sized garage in the back garden. It originally required planning, but in the planning stages permission was refused.
This forced me to reposition the garage in the garden so that I didn't need planning, and this then gave me a wonderful 20m area at the back of the garage in which I can store all sorts (cars, trailers, caravans etc) and also keep them out of view of the house and my wife, which reduces her criticism, shall we say, of my cars!
