Re Vitus 979 - If there ever was a candidate for splitting. Seriously, your bike is such a mixed bag it really would be a challenge to price.
I didn't realise it was a mixed bag, it's 105 throughout apart from seatpost and headset!
I did think of splitting, how much would the frame / forks be worth?
Oh, OK, I was reading from the spec list on your original thread. The problem I have is that I live in France and you can buy 979 & 992 frames over here for less than £100 but a good honest eBay ad with good pics could probably net you double that for a clean frame, which yours looks. All the parts on your bike certainly look clean so will probably do well in their own right, off the top of my head maybe £130 for a nice clean 105 groupset if they are all from the same era. The wheels look good esp the rims so you might get SS interest in the large flanges (LFGSS maybe) so maybe £90+ there. So, you may even double the £200 if you split and will have bits to spare for next project (seat, stem, bars).
I'm splitting my two 992's (bellow links) this year as I just won't get the money I put into them by selling as whole bikes, no way.
