Just got a really nice SL400 with Porcelain Nappa Leather interior. I would like to get the seats as nice as I can but there are marks that won't come out with gentle cleaning. Any advice to get this back to "as new" would be appreciated (or maybe not possible?). Many thanks.

If that's just dirt in the creases than you can remove it with a week detergent mix and a soft nail brush... a few drops of washing up liquid in a small bowl of warm water works wonders.....(I do it on our tan sofas all the time).....and then some leather feed to remove the stickiness of the detergent. If its actually lost colour then paint is the only real option . I've has luck using a fine brush with the correct leather paint and polishing off the excess straight after its dry.

Ive had great success with Colourlock products - the cleaner, cleaning solvent then the coloured repair juice, then the protector. They will colour match for you. Very easy to use and made the bolsters on my E look like new. Very durable as well. (looked very similar to yours in terms of wear - though mine is Alpaca Gray).
I have though just bought the equivalent kit from Furniture Clinic so going to give that a try (for the Alfa which is tan Momo leather - they had a stand at the Classic Restoration show yesterday so couldn't resist!)
As ALFAitalia says but also try putting a damp small hand towel in the micro wave to heat it up then place on the seat where its dirty and gently rub with a little washing up liquid as worked for me in the past
