I have recently purchased an A3 S-Line with half leather and wanted to get the centres of the seats done in similar or contrasting leather. Should i get an old school upholsterer to replace the cloth sections with leather or should I try to purchase a new leather cover kit and get someone to fit it? If so where would be the best place to buy these. There is a Transcal locally who may be willing to supply but I suspect they will be expensive. Any advice appreciated.
