not personally. viewed some doorcards they did which in fairness werent that bad, but the quality of leather used was poor.
all the pics on the website also have really baggy bottoms to the clio seats which is only going to get worse with time.
they also had a trade stand at FCS/trax i think it was, and some of the work was poor. unless you want a small / cheap job doing i'd avoid them
if your talking about D:class ive heard they'e awesome off john2modifed and seen some pics of their work which look perfect
