New E350 Cabriolet 5 Jul. Have been on short trip of 230 mi. Car rides as smooth as 2010 E350 Sport Sedan; maybe because of different suspension. To early to rate mpg but seems to be above rating - I have replaced air filters w/K&N air filters - made big difference on sedan. So far car is solid for a convertible (more so than previous 09 CLK; trunk above adequate w/top down. Performance typical of 350 series. Only negative comment, when p/u'd car the Sirius component of radio not working. Have to order a new module. Isn't this something that should have been caught @ inspection. Had some QC issues on 10 E350 Sedan. Overall, terrific so far.
