Custom auto carpets $$$$$$$

Hello all as my title says I have a chance to purchase a set ,that the print on the box says '' Custom auto carpets , ''240z black complete set '' and they where purchased in the late 80's from a co in Chicago called Jc Whitney and Co . The seller says that they have built in underlay with the set and are still in the box never installed and with the installation instructions included and the asking price is very reasonable . Has anybody ever used these or know about the product

thanxz for any feedback .
