I was car shopping yesterday and saw a vehicle I liked, a Cadillac SRX if thats relevant. In great condition, but the rear seates looked like they just had two car seats taken out of them and the imprints were still prominent. I didnt snap any pictures, sorry. What could be done to get rid of them or improve them? It was very cold outside and it was also clear it hadn't been meticulously detailed yet. The only thing I could think of is to steam them and be generous with conditioner. Any thoughts?
