Have you tried trading it in, cars for cash places as I've been offered more than that and traders have seen my car too!
We Buy any Car quoted me £5285 for this car. I hear tell they also manage to knock the offer down once they see it in the flesh.
I see the add is updated - if I may offer another suggestion? You still say "no silly offers" - of course you dont want silly offers, but you can just say no to them. At least they might serve as a starting point. Another suggestion is to delete "2 children seat fit fine in the back as I use mine with it for the school and nursery runs at times".
That's sending a subliminal message that it's a family car - which, clearly, it isn't. Is your market young parents - or more the "enthusiast" market, like yourself? Or at least someone with the cash to both buy and run it - which is generally more the young professional / no kids / older, more mature person than the family guy.
It also says that it's been used for lots of short runs and we all know that's a bad thing.
Also "Little use as we use family car more often than not, hence sale" says the same - but also says "hey, I need to sell this" - as indeed does " Reason for selling, putting the funds towards main family car". So all the keen-to-bag-a-bargain types will wade in with the silly offers you don't want because clearly you need to sell it. If I was in the market for one of these I'd be starting way low knowing you need to sell the car because the family is taking precedence and the toy has to go. (See what I'm doing there?).
You reinforce this with the "part-ex" section. You'd like a nice fast BM but you still, clearly, are in need of funds - "cash my way". If you can't delete this, then delete the entire ad and start again.
Anyway, why bother telling us why you are selling? You'd be better saying you wanted to sell to buy something bigger and more expensive! Psychologically, anyway. Just leave it out - less is more.
Just take all the extraneous excuses and justifications out - the message you are sending is that you are having trouble selling this as you're trying too hard to justify a high(ish) price and really, really, need to move it on. Just focus on all the good things - and the facts.
I do rather like your amendment about how practical a soft top is in winter tho. And isn't 4x4 such a boon in the snow and ice??? Just a thought.
