So I picked up an 08 M6. The previous owner didnt take the best care of the car, but its not too late to get this car back to mint. The leather probably hasnt been cleaned in a year

so I plan to do leatherique restore a few times to get it cleaned up.
Any suggestions for the best way to take car of this leather?
I really miss the napa leather from my M3 and my wife's X5, I'm suprised they didnt put napa in the M6?

While not a dealbreaker to purchase the car, I'm not a fan of merino vs. napa in the slightest.
