I have and never have had an intention of buying one! Never really 'got' them, although a lot of people use theirs down here and obviously enjoy it. I know a lot of people have bought them over the years as investments and that has probably worked quite well, but at £35k upwards I can't see it now. Single garages go for for around £10k to £12k around here, much better prospect to my mind, and you get a rental income as well. But you can't see the sea.
Don't talk to me about corrosion as a result of living on the coast....spent a fortune on 'marine grade stainless steel for coastal locations ' outdoor lighting a couple of years back, noticed yesterday that they have a thin layer of rust forming. We get a lot of 'sea fogs' here....the cost of living by the sea!!
