I was looking at various e24 cars,with the m6 in particular.What I would like to know if the leather seats used in these cars are of good quality.The reason I ask is because every car I looked at,the driver side seat had an excessive amount of wear(cracking,peeling,discoloration)of the leather.Some of the cars had less than 50k miles on them.Is this something that is common with e24 cars? I know that leather repair can get expensive.
