14. 1966 Aston Martin DB6
No matter the year, an Aston Martin will pull a hefty price tag. This particular model from 1966 is believed to be worth nearly $400,000. Those aren’t small bills.
The DB6 was produced from September 1965 through January 1971, making it the longest production run of any Aston Martin model. In peak performance, it can reach a top speed of 150 mph. But we don’t suggest trying that in the streets of London.
