My mothers house with built-on garage was erected in 1974 (by my late father), a row of 3 big detached houses with a private drive. My dad used to park his Morris Marina in the garage and an Austin Princess too, big family cars. But my mum couldn't get out of her little Suzuki Swift a couple of years back, she now has a Fiat 500, it's easy to get that into the garage but the doors are so big that they clang against the sides, cars have got so fat and lardy.
I have a garage, it's full of bikes, as above, what's the point in putting new cars in them? They don't need weather protection. Look at how many diddly "3 bed executive boxes" turn their garage into a 4th bedroom.
Our cars are outside and luckily for me, I keep my scooter and motorbike in my mother's garage and the 1993 MX5 in the MIL's.
