Hot Wheels Legend Series, released in the late 90s for adult collectors. This is the "Barris Kustom Set 4-Car Set" released in 1998 as the 3rd installment. Set Contents: ・'51 Merc (Hirohata Merc) ・Ala Kart ・'49 Merc ・Elvis Dream Cadillac (Elvis Presley) Based on the 100% series, it features even finer parts 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 and serial card are complete, and the acrylic case with the logo is unopened. I think this is a rare item that is hard to come by these days. If you are looking for one, please take this opportunity.
