I got this light for my R53 Cooper S and the plug in for the harness did not fit the harness in the car. I needed to modify the circuit board and change the wiring harness in my car so that it would fit.
I had a bit of disappointment today when my new hitch arrived - it was not the correct model for my car.
In retrospect, I looked back at the ordering page and found that it was my mistake but I could see why. I searched for a hitch for a Mini-S R53 and it took me to a 1001 which is for a non-S R50. The model numbers for the hitches and the cars they match up with were at the very bottom of the page, which I didn't see when ordering. It would have been very helpful if the drop-down menu had not just the hitch model number (1003) but the car model as well (R50, R53...) to help avoid this confusion.
It cost me return shipping and another week or more of wait. Not fun.
I recently ordered some blackout rings for the tail lights on my F54 Clubman. Aaron and his team provided great service and support when I had an issue - organising a new set sent directly from the distributor to me in Australia. I have ordered from OutMotoring quite a few times over the years and this is the first quality issue I have ever experienced - having said that, with great customer service I have no hesitation in using them again.
