Seems criminal to bin genuine parts at such low mileage, especially with Gadge reminding us of the sad fate of otherwise perfectly good cars being lost to ill-fated engine swaps and body chops...
Does any potential buyer hesitate because of the location, I wonder? You're in Yorkshire, others can be several hundred miles away, and large parts don't ship for free.
In the Reliant Scimitar club, we have what is called Scimaritans, an informal section within the forum whereby anyone going on a fairly long journey is prepared to detour to pick up and deliver bulky items on behalf of other members. As well as delivering the parts you also get to meet members in other parts of the country. In another capacity, when I used to travel regularly back and forth to the Glasgow area, I once picked up a set of alloys for an Aston Martin from a chap in Derbyshire and delivered them to the new owner in Glasgow, and he gave me a very acceptable bottle of my favourite single malt in appreciation.
I'm in Sussex now, but I regularly travel to the west Midlands and Essex, and occasionally to York and Edinburgh. If you don't mind waiting until my next trip, I'm happy to carry bulky bits for not too unreasonable detours.
How do others feel about having a section in the forum where these arrangements might be advertised? Or has this suggestion been made before and not been successful?
