VOLVO has worked very hard to right the old C70 Coupe and Convertible wrongs with the all-inclusive second-generation model, known as the Hardtop Convertible. If you own the old car, you will probably marvel at the dynamic, refinement and quality advances the latest C70 achieves. And the Ford-owned Swede isn’t stopping there, looking beyond luring Saab 9-3 Convertible buyers in the hope of convincing the BMW 3 Series and Audi A4 Cabriolet set that this C70 CC has got what it takes.
