There are less than half the number of Multiplas on UK roads now compared to this time in 2015. 9,097 were road registered at the end of 2014. As of the end of 2017, that figure was 4,272 - a 53% reduction. Year-on-year, numbers are decreasing by around 20-25%. If that trend continues, by the end of 2020 there will only be around 2,000 left. That's all models, round and square nosed.
In the case of the roundnose JTD ELX 115 (which in my view is the best of the Multiplas), last year alone almost a third disappeared from UK roads.
