If you want bullet proof leather care you'll need to do Leatherique about once a year. The manufacturers of Leatherique also sell leather repair kits. You drive a >$80 000 car; I doubt anything from Pep Boys will remedy the problem that you describe. I have been using Leatherique products for over 10 years and can attest to their quality as can many on these boards. Using Leatherique to clean and condition leather is a process, and requires some patience, however, the result is well worth it. Take the time to research and learn from their website:

Decide first if you want to engage in leather repair, anyone can do it, however, it is a process to order the correct materials and dye color. As a moderate DYI'r for instance, I replaced my interior trim with OEM Carbon Fiber, and will use Leatherique to clean and condition my leather, however, I will leave leather repairs to the professionals, as I do with Paintless Dent Repair.
