Questions about the 2018 Lagoon 450

How much is a 2018 Lagoon 450 worth?

A 2018 Lagoon 450 is worth about £330,000 in today's asking prices, most likely between £291,500 and £396,000. Based on 25 comparable boats built between 2015 and 2021, 5 of them in 2018.

What do 2018 Lagoon 450s ask?

The 5 boats built in 2018 that we observed asked a median of £316,500 in today's prices. Each boat is counted once, at its latest asking price; these are asking prices, not sale prices.

Is a 2018 Lagoon 450 cheaper than a 2019?

Yes, usually by about 2.1%: each newer build year of this model asks that much more, all else equal. The gap between individual boats is often larger, because hours, VAT status and where the boat lies move the price too.

How much will it lose next year?

About £6,500, or 2.0%, if the market holds where it is. That rate is fitted on 42 boats across the whole run, not a forecast of the market.

Are these sold prices?

No. Every figure here is built from asking prices seen on public listings. Boats usually sell for less than they ask; we do not yet measure by how much, so we never print a sold price as ours.
