The 2013 Opel Astra Cabrio was spied recently with its top down, while doing some test runs on the Nurburgring racetrack in Germany. So far, no technical details have been revealed about the cabriolet version of the Astra, but we expect it to come with the same engine options as the hard-top model. What we do know is that the Opel / Vauxhall Astra Cabrio is going to have an electrically retractable canvas roof. Opel is expected to put the convertible Astra on sale sometimes next year. Hopefully, this will happen before next summer.
