Corvette Trivia

Both 1968 & 1969 Corvettes came with round parking/turn signal lenses in the front grill before they were changed to a more squarish lens design in 1970. But then 1970 & 1971 both have clear front lenses that distinguish it from the 1972 which had amber lenses. Also 1970 & '71 Corvettes were offered in Mulsanne Blue, just like this one. So how do we know the correct year of this stingray?

Only 1970 offered the Bright Blue leather interior. Corvette dropped the Bright Blue interior option in 1971 and changed it to Dark Blue.

 

The correct answer is: 1970
