As titled i have 2 sets of leather for a sapphire going to mix and match to get the best set ,
or im thinking about getting a full reupholstery done close to original as possible ...
and have also been looking in to having them connollising to see differences in price,
I was thinking about getting the roof lining re trimmed and also the back quarter pannel covers done,
has anyone had retrims done ...
or had there interior connollisiled ( is this worth it or anygood and how long does it last ) ??

Im bacially looking for recommendations and names ..websites or numbers ...

i live in the hertfordshire area, i could supply the car with the interior , or just the interirror on its own
so any help or advise please
