I'm trying to find a driver's or both front seats with adjustable lumbar support.
1st question - when this was purchased from new as an option was there both a manual and electric option? I've heard of the electric option with a pump inflating the lumbar support in the seat but not of a manual style control?
2nd - I think that the front seats from a saloon but not coupe or convertible would fit straight into an E46 Touring - is that correct?
3rd - as finding seats with lumbar support on the 2nd hand market is proving extremely difficult are there any other models of seats that might fit. For example I found this old post about somebody fitting E46 seats into an X5.
The more options I have, the better my chances!
