The Hot Wheels Legend Series, released in the late 90s for adult collectors. This is the "Vintage Record Holders 4-Car Set" released in 1998 as the 4th installment. Set Contents: ・Challenger 1 ・Watson Roadstar ・'57 Chevy 150 ・Willys Gasser Based on the 100% series, it features even finer part separation, interior detailing, and meticulous paintwork even on the underside of the chassis. It's a work that can be called the culmination of Mattel's technology, and I can honestly say that even current RLCs haven't reached this level. It's the pinnacle of quality for 1/64 scale. Rumor has it that the series ended in a very short period of about two years because it wasn't profitable. The outer box, serial card, and acrylic case with the logo are all unopened. I think this is a rare item that doesn't come around often these days. If you're looking for one, please take this opportunity.
