Hello All, after opinions re the 7 speed box on the c320 cdi 2009. any comments : 1. i see some comments re the box "hunting" for gears. 2. Some comment re the box changing up too quickly 3. How do you tell what software the box has , if you can without a diagnostic machine. 4. and one last q, prob will not go down too well around here, should i get an BMW 330d ? Thanks all. Ian.
