Looking at a E92 M3 with all the kit, except heated seats
So, a couple of questions from those in the know;
1) Are the heater elements & wiring loom already in the seats and just not connected, or
2) Any idea how much it would be to retrofit them?
I understand I'll have to add the switches, have them coded etc. so any factual knowledge would be much appreciated.
I also know there will be a load of smart A£s&o$s who'll say 'just buy one with them already fitted', so please, don't bother
