Is a 1986 Ford Ranger considered classic vehicle in 2006?

No, a 1986 Ford Ranger would not generally be considered a classic vehicle in 2006. While it was getting older, the 20-year mark (often used as a rough guideline for classic status) hadn't been reached. The term "classic" usually implies a vehicle with some degree of historical significance and collectible value, which a 1986 Ranger wouldn't have achieved by 2006. It would likely have been considered a vintage or older truck, but not yet a classic.
