Switching from C70 D5 to S80 D5

Hi, I play with the idea to separate myself from my C70 D5 because I get my new MX5 in 6 weeks. Therefore, I am looking for a replacement for the days I don’t want to drive open, need as no winter suitable convertible. Since I was very satisfied with my C70, it should become a Volvo with the beautiful D5 engine again. How different is the C70 from the S80, apart from the platform: How big are the differences between D5 180PS & 5 Gang AT and D5 185PS 6 Gang AT? What has been changed on the engine? Are the seats (and headrests) as comfortable as in the C70? To be continued…
