I think you're making a mistake not getting this done whether you sell or not, you are just handing people the stick to batter you with over the price.
Right from your post i've learn't nothing bar the fact that it needs work so be fair £6k less £500 for the refurb then i'm going to have to get them off and the car will be out of action for say a week minimum if I get my act together so lets call that another £500 and then it is a bit shonky and you don't seem to care so i'll knock another £500 off.
Jb that's not me but there are some shiesters out there who will try and shaft you, my earlier post was gently trying to get you to make a little more effort and not sell it short, it should pay off. But it's up to you.
I would say that prices have firmed up of late and not many up for sale after the panic earlier this year so I would get the shocks refurbed it's worth the hastle.
