Alsn, is that dye or paint? I didn't think vinyl could be re-dyed. Besides Lane, leather isn't supposed to be perfect like Cory said, would there have been perfectly matched leather in a car of the 50's?
I know where you are because I get there all the time, once you take care of the bigger issues on a car the smaller, less significant ones, start to look bigger. I'd hate to see you ruin a perfectly nice leather interior. If anything, price out a new one before you do anything to it, figure you could probably sell the one you have for a bit (I hear theres a guy in PA that builds these things every other week) and use that money toward your new interior. The only time I take drastic measures to "fix" something is when it's already F'd and I can't make it any worse.
