At £80 thats a snatch!
I saw those a while back and I'm sure they were well over £100 so they've come down due to lack of demand. You might be well off buying them, storing them and then grabbing the other bits as and when you can. It's definitely doable as the chap me and SaffV6 know has done it but neither of us can ever get hold of him to ask him about stuff like that but it is definitely doable - I saw his 2L Saff before and after he'd done the work and you'd never know the difference he did such a good job. The only thing he wasn't able to wire in was a heated windscreen but he'd got everything else including the loom for the memory mirrors!
EDIT:
Forgot to mention, when looking for seats the later seats dropped the pocket at the front of the seat behind the legs (something few cars have). It seemed to be a <97 thing where you had a pocket at the front of the seat under your knees but in the 98 onwards it seemed to vanish. It's been present in both 97 safranes we've had and not present in our 98 safrane which has the modern folding head rests. 99 models were the worst IMO - no leccy seats at all
