Eight-person chalet carriage includes a kitchen, living area, bedroom and bathroom, for 32k!
Some parts of the coast you couldn't get a beach hut for that money.
No, they were a lot cheaper than that. The price included the site, so the carriages were probably more or less free. Which may be fair, if their value somewhere isn't a lot more than the cost of taking them there.
And a beach hut is also a lot cheaper than that, wherever you are - just as long as you don't want the right to keep it on a site at a popular location as well.
