    Hi All,

    I am lamenting the passing of my C32 Estate, bad! I replaced it with a C250 CDI Coupe auto which is great but there really is no drama although it is really quick in the gears. Needless to say I have over halved my visits to the pumps but alas something is missing (other than overdraft)

    I notice with much interest C350 CGI Coupes are now selling for a relative 'song' and am intrigued by the road tax being only £170 per year (Band G 164 mg CO2); I pay £135 for the Band F on the diseasel.

    So I am even more intrigued to learn what the real world MPG figures are for the C350. The C250 CDI returns me only 25mpg (wragging) to 31mpg (gently + Eco) on my start-stop 7 mile daily city commute, and with an overall average of 34mpg. This is disappointing when MB's official comparable urban and combined figures are 41 and 52mpg respectively.

    As I barely do any motorway driving (where I do get 46mpg plus), a seed is germinating in my head that it might be worth living with a slightly compromised mpg (again!) and return to the obvious joys of driving a V6 benzina! the same official MB figures for the 306 horse 350CGI are a very respectable 29 and 40mpg (for a 3.5ltr V6) but would love to know what the mpg returns are in the real world.

    Any advice is much appreciated

    If you only have a 7 mile stop-start daily commute, I can't see much scope for enjoying even the performance you now have. Presumably you have speed limits all the way and lots of traffic.

    BTW you are doing short runs and starting from cold so really cannot expect to achieve warmed-up mpg figures.

    Take 40% off your mpg from the 250cdi and there's the answer.

    If the urban figure for the diesel is 41 and you are getting 25-31 it follows you probably aren't going to get the official 29 in the V6 petrol.

    mpg tests are done at 21 degrees C - a figure barely seen in the UK, especially at commuting time.

    Taking 40% off the 250CDI mpg gives 15-19 mpg on commute with an overall of 22 mpg which is what I got from the C32 AMG!

    I am hopeful that a next-gen low emission 3.5 non-supercharged will yield a higher mpg.

    Any C350cgi Coupe owners out there to balance the comments by diseasel owners?

    BTW, surprisingly insurance is within £s (not 10s of £s) of a C250CDI
