I have used Lexol Leather Cleaner and their conditioner on my vehicles with leather for years and it seems to work well. The last was for the 8 years I owned a Mazda 3 at 80K miles the seats looked new. Traded it for Big Blue and immediately gave him a few coats of conditioner, after 1200 miles...
Before I received Big Blue in mid August I had only seen 1 white GX in the wild. Since then I have seen 2 Meteor Showers, 1 White and 1 Heritage Blue in Virginia Beach and a few other GXs. They are slowly trickling in, but still quite rare.
