you must be joking...you won't find a "mint" tan carpet unless you buy new from the dealership in this part of the world. they go for approx 800-1000. as for used. I basically took mine and used carpet dye to change the tan carpet to a desert tan using Duplicolor.
About a 100.00 in dye available from CanTire. Worked wonders on my beat pearl beige carpet.
