Questions about the 1998 Sea Ray 310 Sundancer

How much is a 1998 Sea Ray 310 Sundancer worth?

A 1998 Sea Ray 310 Sundancer is worth about £34,000 in today's asking prices, most likely between £28,000 and £40,000. Based on 22 comparable boats built between 1995 and 2001, 6 of them in 1998.

What do 1998 Sea Ray 310 Sundancers ask?

The 6 boats built in 1998 that we observed asked a median of £33,000 in today's prices. Each boat is counted once, at its latest asking price; these are asking prices, not sale prices.

Is a 1998 Sea Ray 310 Sundancer cheaper than a 1999?

Yes, usually by about 7.3%: 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 6.8%, if the market holds where it is. That rate is fitted on 61 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.
