Dollar~~

Dollar weakness has helped drive commodity and oil prices upward.

Commodity and oil prices are often inversely correlated with the dollar.

A stronger US currency depresses the purchasing power of holders of other currencies, while a weaker greenback renders oil gold or copper imports cheaper.

Car Types

A cabriolet (or cabrio)
- a car body style that has a removable or retracting roof and rear window, known in America more commonly as "convertible". Soft tops are usually made of vinyl or canvas, and folding plastic rear windows are common. Owing to the issue of body flex, cabriolets almost always have only two doors.

A roadster
-two-seat, open car, traditionally without side windows (possibly with pluggable doortops), so that even with the lightweight convertible top raised the driver and passenger remain exposed to the elements. In modern times, the word is often used to describe a two-seat convertible without fixed window frames, especially a light-weight sportscar. Here, the use of the name 'roadster' is more a marketing than a technical one, invoking the feeling of an open-top machine for enjoyment, like those of the past.
