I see that you're putting them on ebay. Don't get excited, I don't need them.
Are you aware though that anyone with manual seats can simply swap their squab and backs onto your bases and hey presto electric memory seats. All they need is to add the loom on later pre facelifts. If theirs are say manual and heated then all that's needed just swaps over in minutes.
Just a thought as the parts alone for the bases make them worth a lot more than £100, or if I had a black interir I'd give you that just for good condition leathers.
Good luck
