I am not aware about leather options for X. I know that you can get a custom made interior any way you want as long as you don't use Spotted Owls, Pandas, etc. You may look it up on Google for the actual cost. If he's on a budget of 10K, then buying a car with as many options as he wants sounds like a good idea. I know that this is a Nissan forum, but what about 4Runners?
