Greetings, Has anyone tried to buy dealer mats for a 1999. The vehicle is bronze with a taupe leather interior. We're missing a rear seat mat. The front mats appear to be about a medium gray color with Lexus embossed in the mat. Of course the dealer says they only sell sets of three and their only color is Ivory PN PT548-48980-08. These mats are not ivory. Any Ideas? TIA Jim Farris
