GMP has a continuing line of 1:24 Buicks planned, with the white T-type being next. As far as the Dub line from Jada toys...they are
steadily releasing new color and wheel combos. Just recently
got the candy apple red metallic, candy green, and the orange GN's. Still looking for the white Dub Shop (model kit) GN. As far as
I've seen, I've got all the others. Never knew how many diecasts
had been made in the 81-87 Regal body style until I started collecting...Good Luck on yours.....
