Hi All, sorry for the slow reply, to answer the above questions it cost £125 all in, although I did pay with real money.... I actually found Colourlock by searching previous comments within the forum so I went there last week, but on visiting its a small unit on a modern trading estate and they have room for one, possibly two cars at a time. Initially I was going to buy their complete kit, at £80, so for the extra it seemed like a no-brainer.
As for colour match, I think its very good and the lady that did the work gave me a bottle of colour to take away in case I need more for the future. They checked the colour from the VIN first, but I guess that just checked that it was indeed Champagne.
It took about 1.5 hours all in. Apparently its Black and Red which are the hardest to match, so I clearly knew nothing, but Champagne presents a little difficulty because the stitching is white, but age/colour turn it black and its nigh on impossible (without spending alot) to get the white back up again. They used the thinnest masking tape to cover the stitching.
As above, I don't have a dog in the fight with regard to the company, I'm just passing on my experience. I posted the same on FB and somebody commented that www.leatherrepaircompany.com were better, but they are up in Hull somewhere and I think he may have had some interest in them as he said he'd done a course with them...anyhow you pays yer money...!!!
Long and the short is I'm happy with it and I think it does make the seats look much younger.....
