I thought I should share this experience with others buying a Marco Polo. There has been a glitch on the Mercedes Benz computer system that is listing standard specifications and charging for them as extras. The standard MP Horizon that I am buying was initially priced at over £62,000 then reduced to the correct list price of £51,900 after I queried the cost and the so-called extras. This has happened with 2 MB dealers in different parts of England (I wanted an off-the-shelf standard model quickly). By the way I did get almost 10% off in the end via Carwow, so I have paid just over £47,000 for a 250 MP Horizon, a big reduction on the first quoted price
