Heavy use is good! A 2009 is alright vinyl, though not where the vinyl is today. Its into the recession period and people were cutting corners to survive. Thus the vinyl went backwards in that era. Todays Syntec vinyl, around 2013 and later, is extremely good and has more ter resistance in the standard non patterned vinyls. The patterned vinyl is pretty, though lacks in durability. If you have used a treatment then we find other Owners before probably have also and usually those degrade the stitching. We would suggest do the best you can to get it to last, then replace them down the road. Then your use pattern and care should be soap, water, scrubbing bubbles and some old fashioned lemon Pledge on occasion.
