Another of my favorite 1:18 scale models is the 1963 Ford Galaxie 500XL by Sun Star. This company has done great things with American cars, replicating such obscure models as the 1953 Nash Airflyte and the Kaiser Henry J. The '63 Galaxie was an excellent candidate, since it was a popular platform for NASCAR racing back in the day and made for lots of opportunities to release in various NASCAR liveries in addition to stock. My personal favorite version is the metallic pewter/champagne one seen here.
Owning this Galaxie has made me want to collect more Sun Star releases, and I look forward to seeing what they do in the future.
