I used to like the manual seats on my 2 litre - much faster than the looooongg wait of the electric motors taking me to my desired setting.
When I was sat in the seat it used to immediately thump to the lowest setting for height when I activated the handle -
can't think why?
I actually had my hands on these very seats last week.. I also discounted them because of the Flimper spec, had they have been heated and manual, I may have entered negotiations with him. He does have the door cards, although not mentioned in the listing??
