I was recommended a product by an upholsterer who works at a bentley main dealer and I've just tried it on the weekend and it's by far the best I've ever gotten hold of. It's actually a german equine product for horse saddles etc and is called Effax leather balm and there is also leather combi. Use the combo first for deep cleaning and feed that leaves it matt look and then use the balm sparingly which gives a light sheen depending how much you use. I used on my sl55 which was bit neglected by last owner and it worked brilliantly, and it only costs £9 per Bottle or tub by mail order. It's worth a google!
