Jamie, here's a thought. You've got a working driver's side and I've got a working passenger's side, how about we make a working pair? Either I sell you the passenger side and replace both of mine with alternatives or you sell me the driver's side and replace both of yours.
Here's a picture of my passenger side. It's not perfect with one small dent and a couple of blemishes but I'd reflect that in the price. BMW quoted me £142 for a new one but I'd let you have it for £90 which would partly fund me buying two new Msport versions.
Let me know what you think.
If I know I can't source a driver's side replacement I'll end up selling the passenger side anyway so I thought I'd give you first refusal.
