Chevrolet Camaro Convertible Concept Preview – 2007 Detroit Auto Show: General Motors took the wraps off the new Chevrolet Camaro concept during last year’s Detroit Auto Show and the response was clear: Build it. GM decided that’d probably be a swell idea, considering that even if a tiny fraction of that interest turns into sales, the 2009 Camaro will be a success. That’s even more likely to occur now that the Camaro Convertible Concept has debuted. The concept sported a soft top, but given the amount of pain GM has gone through to develop a retractable hard top roof, we’re betting that the actual 2009 production model will show up with a hard top.
