What is r² in the regression of given problem?

Problem
An article in Worth discusses the immense success of one of the world's most prestigious cars, the Aston Martin Vanquish. This car is expected to keep its value as it ages. Although this model is new, the article reports resale values of earlier Aston Martin models over various decades.

Decade:	1960s	1970s	1980s	1990s	2000s
Present value of Aston Martin Model (average)	$180,000	$40,000	$60,000	$160,000	$200,000

Based on these limited data, is there a relationship between age and average price of an Aston Martin? What are the limitations of this analysis? Can you think of some hidden variables that could affect what you are seeing in the data?
