This is my first Lexus and first leather interior, I am looking on Sewell for floor mats and have a guy coming to make the front seats look new and I can't seem to figure out if this is Ivory or Ecru leather please help! lol

Hard to tell from pics but it looks Ivory to me. The Ecru has more of a tan color to it. Also I think Ecru only came in the UL models.

yeah its super light almost white so I was assuming Ivory but on Sewell site they show Ivory as almost tan and ecru looks white so i'm all confused. I would agree with you and say Ivory personally.

Per the 2003 sales brochure (link in FAQ thread), ecru and ivory were both available in non CL and UL vehicles. CL and UL (which it doesn't appear you have from the dash) did not come in ivory. If your car is an 04-06, ivory was not available at all.

I just looked at the brochure and it says mystic sea opal came with ecru but the ecru sample they show looks Tan and my interior looks almost white? Is there a way to reference the vin or any other way to know for sure?

The available exterior color/interior wood type/interior color combinations are shown in the 2002 LS430 brochure at http://www.toyotareference.com/lexusls#LS01

I have the Ecru interior and its very light in color.
