Not my cup of tea. But each to their own.
For me, it's the modern (aluminium and the like) vs the more traditional (brown / cream) leather colours. The traditional leathers need either black or one of the wood effect trims. The silver and black more modern leathers work well with the aluminium in my opinion.
I looked at putting the silver coloured leather (dakota is it) in mine and it clashed with the aluminium trim (brushed) so I went with black instead. Also it's easier to keep looking clean.
Either way, it's a great car so if you like it then go for it. All the best.
