In the 1970s alarm bells were ringing in the energy sector as a series of energy crises and rising fuel prices spiralled.

Perhaps the single most breathtaking car of the fall auction season, a 1964 Aston Martin DB5--better known as the James Bond car--sold for $4.61 million to Ohio collector Harry Yeaggy on Wednesday at the RM Auctions Automobiles of London sale.

Buyer's premiums raise the total sale price to $4.61 million.
