Unfortunately, this happens with all leather car seats. Just have to avoid constantly brushing the bolster when getting in the car, especially when wearing jeans or clothing with buttons, zippers, etc.
The good thing about leather is that it can be repaired and re-dyed. Depending on how bad the damage is, it can usually be brought back to almost new. There is likely a good auto leather repair guy near you. Either look online or in the phone book, or ask around at the local dealerships for the mobile service they use for spot-repairing their used cars. These services usually perform minor paint and body work, paint-less dent removal, leather repair, etc. Some are purely a mobile service, others also have a shop where you can bring the car.
