Mine is base line Stingray. Nothing special. I am really disappointed in the way the car is made with some really cheap parts. It's just the way things are done now. Still love the car. Went to a show today and got lots of compliments on it.Honestly you may have to try and adjust how you are getting in or perhaps out of the car. I have noticed that if I do not make a concentrated effort to avoid dragging my body across the seat bolsters I drag my body across them. That will just wear on them over time. You didn't mention which type seats you have . Mine are the competition seats and it's just the nature of the car and the seat. Especially if you can't get the door swung all the way open and you are trying to squeeze into a half open door.
I also added a terry cloth cover to mine and try to make sure the side bolsters are protected when i do have to squeeze in.
