It took about 15-20 minutes to fit. The drivers side vent was 20 seconds. The centre console bit was under 5 minutes, there's three Torx screws that hold the iDrive control in place. The dash took about 10-15 minutes as there are two electrical connectors and they are quite fiddly to undo/redo (especially in the cold!), and refit the trim. I'd strongly advise trim removal tools and a towel or similar to avoid any kind of marks to the interior. Do not pay someone!@ChrisD. How much did it cost to get that fitted, if you don't mind me asking. Or if you did it yourself, how bad was it? I've been tempted to replace the piano black awfulness on my 240. I've found a matte carbon set for £820 which I'd be happy to pay at this point.
