More, what you think it's worth and whether you're prepared to spend loads of money and time getting it right.(if it needs it that is)
As with a lot of auction sites, the more people interested in the item for sale, the higher the final sale price will be depending on how many people are bidding.
Often a cheeky offer to the seller can turn up the goods. Try your luck, you never know.
What i have noticed over the last couple of years is that most things seagull related seem to go in trends. The older stuff seems to be taking over in popularity a bit more than the younger stuff, hence the slightly higher price today compared to a few years ago.
I've been quite lucky with my 3 LS's. All of them were bought quite cheap.One needing quite extensive repair, the others just needing a good clean up and a fresh coat of paint here and there. What i've spent on them is a different matter entirely.
Unless the re-sale value of "little model 40's" suddenly rockets up in the very near future, i'm unlikely to get my money back on them.
That's not important to me.
What IS important is keeping the heritage alive and passing on that information to the next generation.
They're still a nice little motor all the same.Not everyone's cup of tea but i like 'em
Hope you get one soon.
