Questions about the 1986 Sea Ray 390 Express Cruiser

How much is a 1986 Sea Ray 390 Express Cruiser worth?

A 1986 Sea Ray 390 Express Cruiser is worth about £27,000 in today's asking prices, most likely between £19,500 and £35,000. Based on 45 comparable boats built between 1984 and 1989, 10 of them in 1986.

What do 1986 Sea Ray 390 Express Cruisers ask?

The 10 boats built in 1986 that we observed asked a median of £30,500 in today's prices, the middle half between £23,000 and £36,000. Each boat is counted once, at its latest asking price; these are asking prices, not sale prices.

Is a 1986 Sea Ray 390 Express Cruiser cheaper than a 1987?

Yes, usually by about 8.4%: 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 £2,500, or 7.8%, if the market holds where it is. That rate is fitted on 58 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.
