The rarity of this specific configuration makes it difficult to determine an exact number of units produced. However, the overall production numbers for the 1951 Chevy pickup can provide some context. According to available data, approximately 580,000 Chevy trucks were produced in the 1951 model year. Considering the limited availability of the five-window and sunroof configuration, it is likely that only a small fraction of these trucks were produced with this combination.
Given its rarity, a 1951 Chevy pickup with a five-window design and a sunroof would be considered a rare and sought-after collectible vehicle. Its value would depend on factors such as its overall condition, originality, and other unique features.
