[SD987]

Let me start by saying that I've owned nothing but convertibles for the last ten years (just picked up my fourth) and full leather in a convertible makes no sense. Frankly, synthetic leatherette stands up to the abuses of time and the elements better than anything that ever came off an animal.

That being said, my experience with black leather is:

Shows dust and wear much more than tan in the same way that wear shows up on black paint more than silver. Definitely is "hotter" to contend with in warm weather. However if you spill something serious on it, it naturally doesn't show up like it would on tan.

I agree that tan looks nicer, particularly on a dark colored car, and even more so if that car is a Boxster. It does show dirt more (notice I didn't say dust and wear) than black, but not to the point where it's annoying (and I drive exclusively top down).

I've seen the full leather on the 987 and it looks like a maintenance nightmare. When you say tan leather interior I assume you mean the standard 987 package where only the seats (and only parts thereof) are leather. Surprisingly, with my tan interior, I find the synthetic parts more of a maintenance issue, particularly the dashboard, which can tend to look "grimy" if not maintained now and then.

I think Lexol products are pretty universally agreed upon as the best leather treatment.
