I had the amber (blond) interior with a young girl and a dog for three years, never regretted the decision! I agree with others not preferring black interiors....is the amber going to be tough to keep clean?
I had Napa leather, while soft to the touch, it is tough and very easy to clean. My recommendation is that you clean it on weekly basis if you're going to have your dogs in and out of the back seat often, don't let the dirt sit for too long.
If you wear black or blue jeans often, you will want to clean your driver seat on monthly basis, the dye from the jeans does transfer easily.
