I've never used Lexol, but that seems to be the product that most Volvo owners like the most for regular maint. You'll spend ~$16 to buy both the conditioner and cleaner. Not sure how Lexol would work with aged leather - especially the lighter colors.

Personally, I've had excellent experience with Leatherique. I've found both the product and the leather knowledge of the people there to be exceptional. Big drawback is that (comparatively) it's extremely expensive (~$50 shipped for 16 oz. containers of rejuv. oil & cleaner; ~$70 for 32 oz. containers). I'm still not sure if any leather product is worth that much - but again, I'm pleased with the results. Go to their website (www.leatherique.com), read their propaganda, even give 'em a call and ask any questions you may have, and make your informed decision.
