I have a double garage, but never put the car in there, it's more like a massive shed really. There are 2 doors on it and they're not really wide enough for even a Golf sized car, plus it's quite tricky to drive in and out out because of the big slope my drive has.
The garage has about 3 lawnmowers in it, plus gardening tools, normal tools, bicycles, pressure washer, winter wheels (must put them on), garden furniture, ladders, an old TV, car cool box, car cleaning/maintenance stuff, decorating stuff, a potting table, holiday suitcases, boxes for electrical items in the house etc etc, so there's not a lot of room for a car!
