Sold my R50 and no longer need this armrest. Yours for $200 + $15 shipping US Mail parcel post in US. Sells new on out motoring.com for $312. It is in very good condition and is complete with the rubber tray insert. Fits both the gen1 cooper, S. I had it in a clubman recently. It was a tight fit but it went in. There may be a different part number for gen2 cars, but this was in a clubman for a test fit and it was fine. Easy install. Remove 2 seat rail bolts, slide it in place and put the bolts back in. Payment by Paypal.
Best arm rest for the Mini. I have one and it blows away the one they came out with later (which I also have and hate). Good luck with your sale.
Buy it! We can install it at the next breakfast, which would probably be easier than installing at dusk in the gravel parking lot at the MOM cabin after a couple of beers!
Please tell me there were at least several people standing around making Deliverance comments while you were bent over in the backseat!
